Better rendering of the prototype for signal(3).

Eliminate double whitespace.

Mechanically kill hard sentence breaks.

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

Markup nit.

Add signal numbers to signal(3).

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

The previous delta duplicated a significant amount of information
already found in the sigaction(2) manual.

As discussed with the committer of that delta, cross-reference the list
in sigaction(2) instead of duplicating the list of functions that are
safe for use within signal handlers.

Add the list of signal-handler safe functions here too, so people can
find it more easily

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

SIGABRT is *not* the same as calling abort(), so don't claim that it is.

Prepare for mdoc(7)NG.

mdoc(7) police: Nm -> Fn where appropriate.

Use Fx macro wherever possible.

Whitespace only change: trim trailing whitespace.

Use `Er' variable to define first column width in ERRORS section.

Introduce ".Lb" macro to libc manpages.

More libraries manpages updates following.

Remove single-space hard sentence breaks. These degrade the quality
of the typeset output, tend to make diffs harder to read and provide
bad examples for new-comers to mdoc.

$Id$ -> $FreeBSD$

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.

signal() returns SIG_ERR, not just -1. The sys/signal.h header file
provides the cast from -1 to the signal() return type, so no further
casting by programmers should be required.

Document the fpgetprec/fpsetprec functions in their man page.
Add cross-references to the elusive fpsetmask() function to various other

Added missing section numbers to a bunch of .Xr macros, or
converted them into .Fn macros where appropriate. Also fixed
up some minor formatting problems.

Changed the description of SIGSYS to better reflect what
it means when that signal is received. Closes PR# 686.

Fix the synopsis of signal() again. Now it is uglier but correct.
(Declarations of signal that don't use typedefs can't be formatted
in the standard man page form.)

Explain the full story, and make it understandable too.

fix the synopsis to show

| void
| *signal(int sig, void (*func)(int))

instead of

| void
| *signal(sig, func())
|
| void
| (*func)()
