Remove the advertising clause from UCB copyrighted files in usr.bin. This
is in accordance with the information provided at
ftp://ftp.cs.berkeley.edu/pub/4bsd/README.Impt.License.Change

Also add $FreeBSD$ to a few files to keep svn happy.

Discussed with: imp, rwatson

A function which takes no arguments has an argument list spelled (void) in the
world of ANSI C.

Use `The .Nm utility'

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

WARNS=2 fixup.

Be pedantic; we don't know of any shell that provides
"similar but not identical" built-in replacements for
false(1) and/or true(1).

Add a note that some shells may have the command built-in.
(sh(1) indeed does)

Add a cross-reference to builtin(1).

Remove obfuscating details of using the false(1) and true(1) utilities
inside the Bourne shell scripts.

PR: docs/32082

Remove whitespace at EOL.

Fix typo

Slightly re-word sentence to allow using .Nm macro without parameter
Use .St macro instead of hardcoding standard name

Add $FreeBSD$ (and test remote commits after the Freefall upgrade)

$Id$ -> $FreeBSD$

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.
