head(1): Provide long options

Provide long options --bytes and --lines to match -c and -n respectively.
This improves head(1)'s compatibility with its GNU counterpart in a sensible
way.

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 EOL whitespace accidentally introduced in r248393.

Add a couple of examples.

Obtained from: OpenBSD

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.

Added the EXIT STATUS section where appropriate.

Note that this appeared at least as early as PWB UNIX.

Use the literal string 'PWB UNIX', as we still have no .At macro for it.

mdoc(7) police: pedantry.

Make usage message and man page synopsis reflect the fact that -n
and -c are mutually exclusive.

mdoc(7) police: use the default ``file ...'' feature of the .Ar macro.

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

$Id$ -> $FreeBSD$

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.
