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.

Update HISTORY and AUTHORS sections for cut(1) and paste(1)

In an e-mail Brian Walden wrote that:

"GWRL stands for Gottfried W. R. Luderer, the author of cut(1) and
paste(1), probably around 1978. Those came either from PWB or USG,
as he worked with, or for, Berkley Tague. Thus they made their way
into AT&T commercial UNIX, first into System III and the into System
V, and that's why they are missing from early BSD releases as they
didn't get into Research UNIX until the 8th Edition."

So update the HISTORY and AUTHORS sections for cut(1) and paste(1).

Fix confusing example in paste(1)

Paste's man page contains an example for a reimplementation of
nl(1). This example uses the command line
sed = myfile | paste -s -d '\t\n' - -
in order to concatenate consecutive lines with an intervening tab.

However, the way the example uses the switches -s and -d and two `dash`
input files is redundant. There are in fact two equivalent but simpler
ways to achieve the desired result:
sed = myfile | paste -s -d '\t\n' -
uses the same style as the previous example, while
sed = myfile | paste - -
is arguably even simpler and illustrates the final sentence of the
DESCRIPTION.

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.

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.

Sort sections.

Added the EXIT STATUS section where appropriate.

mdoc(7) fixes.

Add support for multibyte characters in input files and delimiter
strings (arguments to the -d option.) This involves backing out paste.c
rev. 1.13 until we have a version of fgetln() that operates on wide
character streams.

Fixed the abuses of .Ql visible on stderr in troff mode.

mdoc(7) police: markup polishing.

Fix typos; each file has at least one s/seperat/separat/
(I skipped those in contrib/, gnu/ and crypto/)
While I was at it, fixed a lot more found by ispell that I
could identify with certainty to be errors. All of these
were in comments or text, not in actual code.

paste(1) appeared at least as early as 32v.

Add another example for using paste(1) since tjr seemed to want more examples
on IRC. This one is to create a colon seperated list of directories from
find(1), suitable for use in the shell's PATH.

Add an EXAMPLES section with three examples. Document the problem with
multibyte characters and the -d option in a BUGS section.

Cross-reference between lam(1) and paste(1). Add a STANDARDS section to
lam(1) indicating that paste(1) is a standard way to do some of the same
things.

$Id$ -> $FreeBSD$

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.
