Mechanically kill hard sentence breaks.

Use `The .Nm utility'

mdoc(7) police:

Avoid using parenthesis enclosure macros (.Pq and .Po/.Pc) with plain text.
Not only this slows down the mdoc(7) processing significantly, but it also
has an undesired (in this case) effect of disabling hyphenation within the
entire enclosed block.

Prepare for mdoc(7)NG.

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

Avoid use of direct troff requests in mdoc(7) manual pages.

Remove blanks lines, replacing them with Pp macros where appropriate.

Add missing description for the dummy -o option.

Add a dummy -s option for SUSv2 compatibility.

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.

$Id$ -> $FreeBSD$

.Sh AUTHOR -> .Sh AUTHORS. Use .An/.Aq.

Use err(3). Add usage(). Various fixes in man pages.

environmental -> environment.

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.

Clean out the BUGS section/comments now that our lpr has a better
option parsing.

Implementing the "lp" command.

This command is required to exist in terms of compatibility with the
Posix 1003.2 specification. It actually invokes the lpr service with
the proper options.
