Sync with src/usr.bin/login/login.access.5.

src/usr.bin/login/login.access.5 should be removed from use
because the whole login.access feature has moved to this PAM
module.

Mechanically kill hard sentence breaks.

Deal with unsafe tab characters.

Remove whitespace at EOL.

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

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.

Remove the version information from `.Os FreeBSD' here. Not only
might it confuse people, but it causes a warning message with
nroff, and no version history mentions a 1.2 version of FreeBSD.

If anything, a ``HISTORY'' section should show which version this
appeared in.

$Id$ -> $FreeBSD$

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.
