Actually at the time I posted the first message, we didn't have git snapshot
of pkgsrc tree, so one might have wanted cvsup or csup to retrieve/update
pkgsrc tree.  For people who don't want to keep growing git repository on
their disk drive, cvsup or csup might be still handy.

For that matter, pkgsrc/net/csup, which is 250K in size, is more harmless
in that it won't install files in an odd location now that we're accustomed
to use pkgsrc (I forgot removing the part populating /usr/local in the
previous patch, BTW), yet it does almost the same job as cvsup program
(last time I checked, the expansion of some less popular keywords, $Log for
one, didn't work correctly).

I can redo the patch to replace it with net/csup or to add WITHOUT_CVSUP
knob.
