three to four.

Note how wait(3) is implemented.

The waitpid(2) function needs neither sys/time.h nor sys/resource.h.

Implement WNOWAIT flag for wait4(2). It specifies that process whose status
is returned shall be kept in the waitable state.
Add WSTOPPED as an alias for WUNTRACED.

Per Regents of the University of Calfornia letter, remove advertising
clause.

# If I've done so improperly on a file, please let me know.

Remove reference to "System call restart" in intro(2). intro(2) does not
have such a reference. Add a reference instead to SA_RESTART in
sigaction(2).

Sort .Xr by section number.

Add cross references to siginfo.3.

-mdoc sweep.

add continued status.

Er, highlight function wait().

Add notes about queued SIGCHLD.

Sort sections.

Sort SEE ALSO references (in dictionary order, ignoring case).

Mechanically kill hard sentence breaks.

Finally document the option to avoid zombie creation
through ignoring SIGCHLD.

mdoc(7) police: "The .Fa argument.".

mdoc(7) police: Tidy up the syscall language.

Stop calling system calls "function calls".

Use "The .Fn system call" a-la "The .Nm utility".

When referring to a non-BSD implementation in
the HISTORY section, call syscall a function,
to be safe.

Add mdoc bits for the new waitpid() WCONTINUED option, and
WIFCONTINUED macro.

mdoc(7) police: Use the new .In macro for #include statements.

Remove whitespace at EOL.

mdoc(7) police: removed HISTORY info from the .Os call.

mdoc(7) police: sort SEE ALSO xrefs (sort -b -f +2 -3 +1 -2).

mdoc(7) police: Er macro usage cleanup.

When "any" acts as a subject, the verb must agree with whatever any is of.

Introduce ".Lb" macro to libc manpages.

More libraries manpages updates following.

$Id$ -> $FreeBSD$

Add $Id$, to make it simpler for members of the translation teams to
track.

The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

.\" $Id$
.\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.

Expanded cross references.

Correctly use .Fn instead of .Nm to reference function names
in a bunch of man pages.

Use the correct .Bx (BSD UNIX) or .At (AT&T UNIX) macros
instead of explicitly specifying the version in the text
in a bunch of man pages.

Correct a bunch of man page cross references and generally
try and silence "manck".

ncurses, rpc, and some of the gnu stuff are still a big mess, however.
