[Groff] Groff-1.19.1 for MS-Windows

[Kees Zeelenberg]

MS-Windows (Win32) binaries of Groff-1.19.1 are available from
http://gnuwin32.sourceforge.net/. Grap-1.30 is included.
This is a relocatable package, i.e. it can be installed in any directory.
Macro and font files are first searched in the default (compiled-in)
directories, and if the file cannot be found there, it is searched for in
the directory obtained by replacing the default installation path by the
actual installation path.
I'll post the patches shortly.
