Hmm, I only changed to git bison today, so I guess I should have all
those changes.

That looks better.  Is there however a way to avoid having duplicated
checked-out repos?  I have git trees of Autoconf and Gnulib lying around
here, I don't necessarily want them another time.  Should I just remove
those repos again and turn the directories into symlinks?  If that is
ok, then maybe that could be documented as an alternative, too.

BTW, I should have been more explicit in the above: please fix the
savannah bison pages to not show the CVS tree for the code any more,
and let README-hacking point to the savannah git page for bison.

Dunno, I've not needed the latter much either.

Thanks!
