I checked this out, and it's not possible.  Our test hive 'minimal'
was specially constructed so it does not contain anything
copyrightable.  'large' was constructed from 'minimal' by a mechanical
process.

Nevertheless Digital Corpora looks interesting and useful.  I need to
see if we can add tests (including for libguestfs) that would use that
for people who had downloaded the corpus themselves.

OK.  The patch is the sort of thing I was suggesting.  This is going
to be combined with the revised patch series?
