Style nit: group together optional flags under the one Fl macro.

Clean up malloc(3)'s argument. Remove casts which do nothing when we're
using sizeof() anyway. Use slightly more consistent (per-file) error
reporting for malloc(3) returning NULL. If "malloc failed" was being printed,
don't use err(3). If a NULL format is being used, use err(3). In one case
errx(3) was being used with strerror(3), so just use err(3).

Use `The .Nm utility'

Remove WARNS?=2 and -Wall. WARNS?=2 is going to be the default.

Style improvements recommended by Bruce as a follow up to some
of the recent WARNS commits. The idea is:

1) FreeBSD id tags should follow vendor tags.
2) Vendor tags should not be compiled (though copyrights probably should).
3) There should be no blank line between including cdefs and __FBSDIF.

Warns cleanups. Add missing prototype.

Remove whitespace at EOL.

Fix typo: compatability -> compatibility.

Compatability is not an existing english word.

$Id$ -> $FreeBSD$

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.

Clean up some ambiguous nested if/elses.

Pairs are inherently even.

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.

Close PR#1455. In a couple of weeks, I'll change bsd.lib.mk to use
tsort -q as well - I don't feel like adding tsort as Yet Another Item to the
bootstrap target.
