Deal with double whitespace.

Use `The .Nm utility'

Remove whitespace at EOL.

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.

Import keylogin.

This is the program used to loadsecret keys into the keyserv on the

Note: on some platforms, keylogin is automatically invoked by
/usr/bin/login. We don't have any burning need for this yet.
