For all download helpers (except wget), we force-remove the local copy
(clone or checkout) before cloning/checking out, in case there were some
leftovers from a previous run.
The only phase that can still be interrupted is creating the archive
from the local copy. Even for git, this is not correctly handled:
cvs: tar czf "${output}" "${repodir}"
git: gzip -c "${output}.tmp" >"${output}"
hg: ${HG} archive [...] "${output}"
svn: tar czf "${output}" "${repodir}"
which leaves open a (small) window were we could have a problem.
Only wget gets it right:
mv "${tmpfile}" "${output}"
So, yes, we can do better. I'll fix and resubmit.
Thank you!

Yann E. MORIN.
