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.

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 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.

Remove stale references to utmp(5) and its corresponding filenames.

I removed utmp and its manpage, but not other manpages referring to it.

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

Expand *n't contractions.

Sort sections.

Document missing multibyte character support in utilities specified
by POSIX.

mdoc(7) police

Submitted by: ru

Change the default behaviour of talk(1) to use "localhost" as the
"machine name" in ntalkd(8) request packets, when the destination
and source are local.

This should make talk(1) use much more pleasant for those security-
conscious individuals who have chosen to bind talkd to "localhost".

Previous to this change, talk(1) would require that the hostname of
the machine, as retrieved by gethostname(3), resolved to a valid and
reachable IPv4 address, using gethostbyname(3).

This makes talk(1) dependent on a valid host entry for "localhost"
in /etc/hosts (or the Domain Name System).

PR: bin/23178
Submitted by: angui.sh admin (with cleanups)

Add a reference to talkd(8) as a hint that talk(1) depends on a
service to work correctly.

mdoc(7) police: Deal with self-xrefs.

mdoc fun: add a few more sentence breaks.

Clear local screen when ^D is typed.

nroff and pr no longer try to disallow messages.

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

mdoc(7) police: remove extraneous .Pp before and/or after .Sh.

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.

Nm talk -> Nm.

Partially back out previous fix (in cases ':' and '!'),
leave case '.' as valid user name, not host reference.
Document new behaviour.
