Scheduled mdoc(7) sweep.

Document when this function came into FreeBSD.

mdoc(7) police: Use the new .In macro for #include statements.

mdoc(7) police: Er macro usage cleanup.

Introduce .Lb macro to libutil manpages
Sort .Nm values in some manpages
Remove explicit note about compiling with -lutil, it's implicitly
declared by .Lb macro now.

Fix some spelling errors.

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.

Add the "use -lutil" line to all functions that require it so people like
Dan Papsian <bugg@bugg.strangled.net> don't anger wpaul and myself with
silly linking errors.

Fixed missing include in synopsis.

Removed superfluous quoting of function name in .Fo macro. My synopsis
checker doesn't understand it.

Connect fparseln(3) for mailwrapper(8)

This commit was generated by cvs2svn to compensate for changes in r54820,
which included commits to RCS files with non-trunk default branches.

Import fparseln(3) from NetBSD. It's used for easily dealing with \
escaped lines etc. (used by mailwrapper)
