[Groff] new version of RUNOFF.git

[Bernd Warken]

A new version of RUNOFF.git in github is now published.  Get it with
git clone address@hidden:RUNOFF/RUNOFF.git

It has become quite large now, 464.3MiB unpacked with 12134 files.

It now contains most internet files related to RUNOFF, with
- many files written in RUNOFF
- and a lot of documents, many of which could not be processed so far.

But runoff.7 might be good enough for a first version of a RUNOFF
predecessor.
