In this case -g is equivalent to -rx.

This one is indeed simpler.  However, one typically needs to get the
commit id in addition to the hash, so it seems that in practice, most of
the time, we’d still need to do:

  git clone http://…
  cd foo
  git log | head -1
  guix hash -rx .

so we have both the commit id and the content hash.

WDYT?

Thanks,
