Make this code WARNS=6 clean again (after GCC 3.1.1 import).

Submitted by: Marius Strobl <marius@alchemy.franken.de>

Consistently use __FBSDID

o __P has been reoved
o Old-style K&R declarations have been converted to new C89 style
o register has been removed
o prototype for main() has been removed (gcc3 makes it an error)
o int main(int argc, char *argv[]) is the preferred main definition.
o Attempt to not break style(9) conformance for declarations more than
they already are.
o gc some #ifdef sun ... #endif code

Approved by: arch@, new style(9)

o Correctly define rcsid.
o Add consts where appropriate.
o Rename some variables that were shadowing global declarations.
o Remove register storage-classes.
o Make errmsg a const, so we can just set error messages instead
of using sprintf/strcpy.
o Set WARNS=2

Use PATH_MAX rather than MAXPATHLEN. Also fix a possible off by one
error caused by the -1 being on the wrong side of the comparison.
This would not cause an overflow, as near as I can tell, because we
truncate later anyway. We'd just fail to get a diagnostic for 1024
and 1025 byte file names.

$Id$ -> $FreeBSD$

sccsid -> rcsid and fix some minor nits.

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

-Wall cleaning.

Remove trailing whitespace.

Reviewed by: phk

You will find enclosed some changes to make gcc -Wall more happy in
/usr/src/bin. Note that some patches are still needed in that directory.

I (Joerg) finished most of Philippe's cleanup. /bin/sh will still
need *allot* of work, however.

Added $Id$

use umask 077 for buffer file

Fixed range address bug: 1,2, == 2,2 not 2,.
Overhauled the name space, reworked some modules and removed the
obsolescent Addison-Wesley copyright.

Only a single slash (/) is now necessary to repeat a search as per Theo's
request. So the command:
/pattern/;/
finds the second line containing "pattern" after the current line.
Caveat: The commands `st' and `sr' are now both legal and have very
different meanings. This is because ed(1) extends POSIX to include the
old Berkeley syntax s[rgp]*.
(So should two slashes still be required in the case of the substitute
command, as SunOS ed does?)

Nullify pattern after failed regcomp

added (unsiged) cast to avoid int overflow
removed REGEX directive

fixed undo within a global command (would corrupt the buffer)
changed move within a global to behave as in SunOS
added a couple error messages

This commit was generated by cvs2svn to compensate for changes in r16,
which included commits to RCS files with non-trunk default branches.
