[PATCH] groff-1.20.1: [troff] suggest to use option -V for --version

[Jari Aalto]

GROFF VERSION:
groff-1.20.1

MACHINE:
i386

OS:
Debian testing

COMPILER:
g++ (Debian 4.3.3-3) 4.3.3

INPUT FILES:
<none>

COMMAND LINE:
<none>

DESCRIPTION OF INCORRECT BEHAVIOUR:
Version option change from -v to -V

SUGGESTED FIX [optional]:
It would help if programs could in some extent unify the UI, so that
options would be closely the same. It is common to consider option -v as
synonym for --verbose. An observation, that is based on everyday usage
of GNU programs (cp -v, mv -v ...).

>From user perspective, unifying the command line options would be a good
thing, thus I propose changing -v option to uppercase -V. The -v and
--verbose could be reserved for later user [1].

The patch below acommplishes this.
