bin: Remove ancient SCCS tags.

Remove ancient SCCS tags from the tree, automated scripting, with two
minor fixup to keep things compiling. All the common forms in the tree
were removed with a perl script.

Remove $FreeBSD$: one-line nroff pattern

Remove /^\.\\"\s*\$FreeBSD\$$\n/

Renumber copyright clause 4

Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

echo(1): Clarify portability and mention literal "--" handling.

MFC after: 1 week

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

- Import the HEAD csup code which is the basis for the cvsmode work.

Add the new standard EXIT STATUS section where appropriate.
Sort standard sections in the (documented) preferred order.

/*- or .\"- or #- to begin license clauses.

Mechanically kill hard sentence breaks.

Remove clause 3 from the UCB licenses.

Note that -n and \c are implementation-defined as per TC1 to POSIX 2001.

Refer to 1003.1-2001 in the Standards section now that TC1 allows the
traditional BSD behaviour (-n option) and FreeBSD extensions (\c).

mdoc(7) police: utilize the new .Ex macro.

mdoc(7) police: split punctuation characters + misc fixes.

mdoc(7) police: use the new features of the Nm macro.

Correct some hard sentence breaks. Only those surrounding the previous
commit and those which cause ugly nroff output have been fixed, since
the purpose of the style guideline which they contravene is to reduce
the sizes of deltas.

Improve shell documentation:

* Consistently misspell built-in as builtin.

* Add a builtin(1) manpage and create builtin(1) MLINKS for all shell
builtin commands for which no standalone utility exists. These MLINKS
replace those that were created for csh(1).

* Add appropriate xrefs for builtin(1) to the csh(1) and sh(1) manpages,
as well as to the manpages of standalone utilities which are supported
as shell builtin commands in at least one of the shells. In such
manpages, explain that similar functionality may be provided as a
shell builtin command.

* Improve sh(1)'s description of the cd builtin command. Csh(1) already
describes it adequately. Replace the cd(1) manpage with a builtin(1)
MLINKS link.

* Clean up some mdoc problems: use Xr instead of literal "foo(n)"; use
Ic instead of Xr for shell builtin commands.

* Undo English contractions.

$Id$ -> $FreeBSD$

Various spelling/formatting changes.

Submitted by: Philippe Charnier <charnier@xp11.frmug.org>

Correct use of .Nm. Add rcsid.

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.

Well, it would appear that the "ayes" have it (though by a slim margin).
Apply my \c changes to echo. It should also be noted that this is:
A) going into 2.2, not 2.1
B) a functional no-op unless you actually use it!
