644 68. FIONREAD argument is int everywhere except on SunOS where it is long.

669     > junk a b c d

816    doesn't get <cntl-c> and <cntl-z> signals.
817    It can only be killed from another session. (beto)
818    > cat > foo
819    #!/bin/csh -f

82856. history > 1000 fix (beto)
82955. 6.02.07 9/18/92
83054. Added e_stuff_char() to put back a character in cooked mode in
831    the input stream... Useful for status (^T)
83253. $? == $status and $# == $#argv like in the bourne shell.
83352. Added $dirstack. Problems: off by one since =0 == $cwd, but 
834    $dirstack[1] == $cwd... Suggestions welcome.
83551. Leading spaces would confuse the run-help function.
83650. Don't expand imported environment variables:

96646. 6.01.06 (3/7/92)
96745. complete styles are ignored after shell metachars eg.

969    > mail christos < [tab]
970    completes filenames.

977    environment variables.

98435. sysv_echo is gone too. Now we have a variable called echo_style

986    the builtin echo_style. The default is "bsd" for systems with
987    SYSVREL == 0, "sysv" otherwise. This can be overriden in config.h
988    by defining ECHO_STYLE ro be BSD_ECHO, SYSV_ECHO, BOTH_ECHO, 
989    or NONE_ECHO.
99034. asynchronous notification in run-fg-editor would try to change the 
991    tty settings and print an extra prompt.
992    > set notify 
993    > sleep 10 &
994    > vi^Z

100328. sysv_echo addition; deleted bsd_echo which is now the default.
100427. dunique could crash.
100526. Don't clear lines after an asynchronous notification, because it
1006    might erase the message.

102111. Changed w_ fields in tc.who.c to who_ to avoid redefinitions in
1022    <sys/wait.h> in some os's.
102310. Setting savehist to an empty string makes savehist use the value
1024    in $history.
10259.  echotc did not use the internal termcap descriptions.
10268.  echotc did not work right for single argument termcap strings.
10277.  DGUX needs SAVESIGVEC, updated type protection, and disabled CSWTCH.
10286.  Changed SVID to SYSVREL, since there is no SVID == 4 (yet).
10295.  Typo in tc.sig.h: UNRELSIGS was not getting defined.
10304.  Globbing bug fix. tglob() should ignore globbing characters inside 
1031    backquotes otherwise things get expanded twice:
1032    % echo 'bar?' > 'foo?'
1033    % echo `cat foo\?`
1034    echo: No match.
10353.  Mach setpath fix.
10362.  Alliant process group fix.
10371.  Xenix fixes for broken vi and help path with no suffixes.

1165    leave dangling pointers, that endpwent() will trash.
116611. ChangeSize is now responsible to set the screen size to something
1167    sane, but it should not affect the environment if the information
1168    it received is not valid
116910. Find out if we are running under emacs using $TERM. It is more 
1170    reliable.
11719.  tcsh was broken if SHORT_STRINGS was not defined (glob() problem)
11728.  If GetSize() fails it should always return reasonable screen sizes.
11737.  globbing should not fail if one or more patterns match.
11746.  increased the number of aliases in the loop detection code.
11755.  DGUX has size_t and pid_t defined now...
11764.  ESIX does not have EWOULDBLOCK or EAGAIN & POSIX... That was not handled
1177    correctly.
11783.  rs6000 needs BSDWAIT.
11792.  Hpux susp key could not be changed.
11801.  Apollo fixes.
1181
1182V6.00.00, 07/04/91
118345. Fixed quoting of VSTART/VSTOP on termios
118444. Memory leak every time you pipe in or out.
118543. echo {foo bar.[ch]}. Did not check for end of word.
118642. ANSI prototypes
118741. dmove() would leave the source descriptor open when using dup2()
1188    e.g.
1189    while (1)
1190	echo foo >>! bar
1191    end
1192    runs out of file descriptors
119340. recursive `` expanded via aliases would abort.
119439. set home=../relative-path-name was broken.
1195    e.g.
1196    set home=../..; cd ..;
1197    <abort>
119838. Incorrect error when changing to directory:
1199    e.g.
1200    mkdir not-in-cd-path; chmod -x not-in-cd-path; cd not-in-cd-path;
1201    echoed:
1202       not-in-cd-path: No such file or directory.
1203    it should have said
1204       not-in-cd-path: Permission denied.
120537. if ( \! =~ [\!] ) echo ok, did not echo ok. Quoting inside [] pattern.
120636. More than 127 jobs caused job # to go negative
120735. unsetenv <pattern> ... Added support for more than one pattern.
120834. More background process status report fixes.
120933. Apollo builtin support.
121032. Glob fix. echo '*' * was not handled properly.
121131. Glob fix. setenv FOO `sleep 1` would either cause a segmentation fault.
1212    or print ambiguous.
121330. Glob fix. Quoted characters inside [] were not handled properly.
121429. Removed TELL and VMUNIX defines. I think we cannot compile on V6 anyway
121528. Overflow check for expansions.
121627. Added matchbeep, shell pattern history searching.
121726. Added code to handle /dev/std{in,out,err}
121825. Fixed POSIX speed handling in raw mode.
121924. Fixed a flushing bug in the filec code in sh.file.c
122023. Compiled and added hp9000s700 to the list of hosts.
122122. Fixed horrible bug in gmatch() 
1222	switch (4)
1223	case [a-z]:
1224		echo bug;
1225		breaksw;
1226	case 4:
1227		echo ok;
1228		breaksw;
1229	endsw
123021. Fixes for _SEQUENT_ ut_host.
123120. FLUSHO added
123219. mkdir foo\`bar; cd foo\`bar; was broken
123318. EWOULDBLOCK == EAGAIN on RENO check for that too.
123417. Dword() simplified and removed the gotos.
123516. Hpux now compiles with POSIX. Moved the local chars modes in ed.init.c
1236    after the tty modes.
123715. Process group fixes for POSIX
123814. We need <sys/filio.h> on the suns for FIOCLEX!!! We did not close
1239    our file descriptors before...
124013. A/UX fixes.
124112. History events that start with a number are not necessarily numeric:
1242    > !3d
1243    3d: Event not fount
124411. History loop detection added.
1245    > alias a \!#
1246    > b; a
124710. Alias loop detection code was ineffective on eager optimizers.
1248 9. All errors should now go through our table. Next step we should
1249    add nls error messages.
1250 8. Unsetenv now globs its arguments! Before it did not...
1251 7. Added tilde cache and -l flag.
1252 6. Added autocorrect
1253 5. Fixed for so that background jobs in scripts get process groups
1254 4. Fixed amazing memory leak in setenv()...
1255 3. Added short2qstr() so that we can form quoted strings to be used with glob()
1256 2. str2short and short2str allocate space dynamically.
1257 1. Fixed bug related to the is*() routines called with shorts.
1258    [only if NLS and SHORT_STRINGS are defined].
1259    (The _ctype_ was getting indexed with shorts...)
1260 0. Complete overhaul. Brought in the 4.4 csh stuff. Separated most
1261    tcsh and csh code except where I would have to add more global
1262    variables. Compiled correctly with both lint and gcc -Wall on
1263    a sparc running 4.1
1264
1265V5.20.03, 03/20/91.	- Never released
126625. Kanji, SXA additions.
126724. (exec foo) should not fail if they are suspended jobs.
126823. Support kernel paging stuff on aix 370.
126922. Now we handle correctly the environment variables LINES, COLUMNS,
1270    TERMCAP for window size changes...
127121. Tcsh 5.18c+ had broken NULL chars on scripts.
1272    > cat > foo 
1273    #!/usr/local/bin/tcsh -f
1274    echo "foo"
1275    echo "^V^@"
1276    echo "bar"
1277    ^D
1278    > chmod +x foo; foo
1279    foo
128020. Posix has EAGAIN and not EWOULDBLOCK
128119. Don't set ECHOK; makes kill ^U ugly.
128218. $shell is SHELLPATH and not $SHELL any more.
128317. Added -n flag to cd, pushd, popd and dirs. Documented -l and -v
1284    flags.
128516. Documented and fixed chase_symlinks and ignore_symlinks.
128615. Call endpwent() when you get interrupted...
1287    cd ~chri<tab>^C
1288    cd ~christos/<enter>
1289    <stuck>
129014. Exec when you have suspended jobs asks for verification.
129113. Variable length fixes:
1292    >set abcdefghijklmnopqrstuvwxyz=1
1293    >echo $abcdefghijklmnopqrstuvwxyz
1294    abcdefghijklmnopqrs: Undefined variable
1295    Now we have better messages too...
129612. Icon fixes...
129711. Quote expanded glob and history chars too.
129810. If someone sets SHIN to O_NDELAY we died... Now we set it back...
1299 9. unset path; unsetenv PATH; ls-F; (poof) fixed...
1300 8. Patches for masscomp, and ${var123} lexical analysis fix...
1301 7. Patch for sunview bug: A partially covered suntool sends SIGWINCH every
1302    time the text is scrolled, causing annoying redraw effects. Now tcsh
1303    checks if the size really changed before doing anything.
1304 6. Interrupt in the middle of cwdcmd, and periodic does not remove the
1305    aliases.
1306 5. prompt2 and prompt3 fixes:
1307    Prompt2 now prints the status of the parser by default.
1308    Prompt3 can now have the standard prompt escape sequences.
1309 4. eval file descriptor re-direction fix.
1310    >set p='w | tail +3'
1311    >eval $p
1312    (originally | tail +3 was ignored)
1313 3. $edit != emacs anymore; it was misleading, 'set edit' enables editing
1314    'unset edit' disables it.
1315 2. PERROR define fix. 
1316 1. irix3.3.1 line discipline fix.
1317
1318V5.20.02, 12/15/90.
131932. /etc/Logout added and merged with /etc/Login flag.
132031. Fixed tty chars in ed.init.c. Some of them were not handled correctly.
132130. Command execution does not leak memory any more, and doing
1322    ~ four times does not core-dump.
132329. Fixed the notorious csh 'if(' bug (part of the convex fixes)
132428. Intelligent getwd() on startup, and canonicalization.
132527. Intelligent directory stack. Gets updated when $HOME changes.
132626. Directory stack/save-restore additions
132725. Convex Fixes.
132824. Fixed onlret, and echonl getting stuck on svid.
132923. Shouldn't leave tty in raw mode at auto-logout (e.g. when su'ing from a
1330    csh, this is annoying).
133122. Some users had environment EMACS set to something, and with my bad fix
1332    at pl 1 found that they didn't have echo... (of course, even before my
1333    "fix", they didn't have editing...). Anyway, refined the check to be
1334    for EMACS=t, which is what emacs sets when running a subshell.
133521. kill -CONT %job, would not update the status of the job, but it would
1336    just restart it.
133720. Sequent fixes.
133819. AIX370 signal and TCF fixes.
133918. fixed ls-F -l, SIGINT problem.
134017. aix on the ps2 does not have strcoll() either.
134116. Bind [A - [D and OA to OD in vi mode to the arrow key functions
1342    so that they work from insert mode.
134315. %~ was not working correctly for /home/news and /home/newsbin...
134414. Removed Rcs Log
134513. ISC unix fixes.
134612. sunos3.x wants <sys/dir.h> not <dirent.h>
134711. Remove precmd's, cwdcmd's and periodic cmds that had errors.
134810. Compile sunos4.1 using termio. 
1349 9. Rs6000 line discipline fixes. 
1350 8. T_Tabs was wrong for termio machines.
1351 7. Don't bind single keystroke arrow keys, when they are already bound!
1352 6. Test for newline and tab before deciding not to send shell scripts
1353    to the bourne shell.
1354 5. Added LITERAL prompt stuff.
1355 4. Fixed gethostname() in sh.rest.c to return the nodename.
1356 3. Do not quote spell checked stuff. This is not very intelligent but
1357    works better than before.
1358 2. Fixes for relative path components. (paths that start with a .)
1359 1. Fixed so that Rawmode() is not called when we are not editing
1360    (breaks running under emacs)
1361
1362V5.20.01, 11/15/90.
136312. Recognize environment variables too.
136411. Always start in Rawmode()
136510. don't try to execute binary files using the bourne shell.
1366 9. Vi change to end of line updates correctly now.
1367 8. Prompt in continuation lines.
1368 7. Prompt in if statements fix.
1369 6. System V ^C works right now.
1370 5. ^Z works correctly in bindings
1371 4. Better error messages for variables.
1372 3. dinit() now is more robust.
1373 2. Added aux2.0 patches.
1374 1. Fixed bug with arrow key bindings in ed.screen.c. All the keys
1375    were bound to up-history!
1376
1377V5.20.00, 11/10/90.
137826. Fixed system V and POSIX time reporting.
137925. Fixed ed.screen.c so that it does not use malloc().
138024. Fixed SIGWINCH on the iris
138123. Fixed ed.screen.c, so that settc works correcly. It used to set
1382    the termcap with a string that was allocated from the stack!
138322. Fixed listing of commands, where the last command was not checked.
138421. Fixed which command. It did not work for
1385    \<command>, if command was aliased.
138620. Eliminated CSH4.3 define. You've had enough time to upgrade from 4.2
138719. Fixed GotTermCaps to be called only once.
138818. Added bindkey -r
138917. Attributes were not getting reset correctly.
139016. history -t does not print the time-stamp.
139115. AddXkey, works now for single character xkeys.
139214. filetype() knows better about symlinks.
139313. ls-F works with filenames that have metachars
139412. Completion/spelling works with quoted things.
139511. Fixed refresh bug. Repeat by:
1396    On an intelligent terminal that has insert and delete chars (xterm)
1397    > orphan
1398    > vi orphan.c
1399    > ^P^P
140010. Fixed so that if we don't have a tty on stdin editing is disabled.
1401 9. Check for nested process forking, to avoid loops such as:
1402    > alias foo 'set bar=`foo`'
1403    > foo
1404 8. Fix setting of AsciiOnly (Per)
1405 7. tw.spell.c, defined F_OK for systems that don't have it.
1406 6. ourwait.h had typo in ifdef.
1407 5. BSD compilers need a cast to int for enums used in 
1408    switches (Matthew Day)
1409 4. Found the cause for the core-dump in long backquote 
1410    expansions (Mark Davies)
1411 3. Some externs in ed.h needed to be truly externs...
1412    reported by Mark Davies, bug appeared only on hp9000s800.
1413 2. Changed $tcsh, and $version strings.
1414 1. Added internal sprintf function, renamed putchar to CSHputchar,
1415    printf to CSHprintf, sprintf to CSHsprintf.
1416
1417V5.19.02, 10/23/90.
141836. Added /etc/cshrc for the SGI irises.
141935. Added expand-variables function.
142034. Documented $time in tcsh.man
142133. Shell variables are now 'recognized' when expanding/listing things.
142232. ls-F does not eat the last slash on the / directory!
142331. Strings bound to keys are printed inside double quotes.
142430. History now remembers the exact line, not just an unparsed version of
1425    the tokens.
142629. Renamed itoa to Itoa(), so things in libc that use itoa() don't break.
142728. Ported to IBM aix/ps2. 
142827. Fixed eval so that it forks when the output is piped
1429    Repeat by:
1430    > who | grep $user
1431    > eval who | grep $user
143226. Fixed so that 'nice <builtin changing the working directory>' does not
1433    nice or fork.
1434    Consider doing:
1435    nice cd /tmp && rm *.c (don't try it!!!)
1436    [what actually happens is that nice has to fork, then the child executes
1437     chdir, and the parent stays where it was]
143825. Added Dan's patches (nls, builtin bindkey, fixes to the editor).
143924. Added aix370, migrate, getspath, getspath, getxvers, setxvers
144023. Added builtin echotc, removed sl and el.
144122. Ported to 4.4 BSD. This involved changing the way lots of flags worked,
1442    cleanup of the SVID stuff, and addition of more compilation flags.
1443    Now POSIX can work whed BSD is defined...
144421. Fixed so that el, sl work. Actually they are to be removed soon and
1445    be replaced with echotc.
144620. Avoid the Quoted Space hack for alias when printing jobs!
1447    [aliases to the same name avoid further alias expansion, by 
1448     inserting a quoted space in front of the command. In SHORT_STRINGS
1449     QUOTE is the 15th bit so print ignores it thinking it is the
1450     end of the string. So we just skip the Quoted Space....]
1451    Repeat by:
1452    > set notify
1453    > alias ls ls -F
1454    > (ls) &
1455    Prints        Exit 0 (
1456    Should print: Exit 0 ( ls -F )
145719. Fixed so that "", '', ``, all produce ': Command not found',
1458    and not the spurious messages.
1459    Repeat by:
1460    > set path = (/bin /usr/bin .... .)
1461    > ""
1462    /some/path/name/: Command not found
146318. Enable the use of <ctype.h> macros if they exist and NLS is defined.
1464    NLS code is not ready yet.
146517. Fixed rmstar and continue_jobs code, so that they are not compile
1466    options, but shell variables. Now you need to 'set rmstar' to get
1467    enable rmstar.
146816. Fixed SIGWINCH, SIGWINDOW, and setting of li, co, that broke
1469    suntools, and others.
1470    Repeat by:
1471    Start a shelltool of size other than 80x34
1472    > telltc
1473    > stty -a
1474    do not report the same number of lines and columns.
147515. More fixes to tw.parse.c, and tw.spell.c.
147614. More fixes to sh.char.c.
147713. Fixed coredump caused by ``.
147812. Fixed spell-line code..
147911. Trapped SIGCHLD in sh.sem.c, while forking. Still there is a small
1480    race, but the probability of happening is smaller!
148110. Fixed sh.char.c to be ISO compliant.
1482 9. Added expand-glob
1483 8. Fixed ourwait.h for little endians.
1484 7. Fixed that foreach i (^D expands correctly.
1485 6. Fixed so that listmax is ignored in ls-F.
1486 5. Fixed spelling correction so that single letter words and words that
1487    contain globbing chars do not get spell checked.
1488 4. Changed NeXT HOSTTYPE to next, since all HOSTTYPE's are lower case.
1489 3. Fixed symmetry, and changed symmetry HOSTTYPE from sequent to symmetry.
1490 2. Added boldfacing, underlining chars.
1491 1. Added IRIX3.3.1 support.
1492
1493V5.19.01, 9/26/90.
1494 7. Brought the README file up-to-date, and changed the bug report
1495    address to point to me.
1496 6. sh.lex.c. In addla(), overflow computation was wrong.
1497 5. Fixed SHELLPATH, to be set correctly when $SHELL is not set.
1498 4. Fixed print statement in sh.proc.c that contained \215.
1499 3. Fixed the Makefile and MAKEDIFFS so that a tahoe diff can be made.
1500 2. RS6000: hacked around execv bug, and ed.init.c warning.
1501 1. Editor should not be enabled when we don't have a tty.
1502
