Re-enable building of Groff documentation; texinfo has just been
upgraded to version 4.5.

Upgrade to Groff 1.19.

Upgrade to Groff 1.17.

Build and install groff(1) texinfo(1) documentation.

Upgrade to version 1.16.1.

Allow devhtml and grohtml to be built.
This is a new feature of groff and is a html driver for groff.

From the manual page:
"grohtml translates the output of GNU troff to html."

This is very interesting for people working on documentation.

Allow grog to be made during compilation.

$Id$ -> $FreeBSD$

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.
