When a downloaded ref doesn't contain a sha1, the error message displays
a random sha1 because of uninitialized memory. This happens when cloning
a repository that is already a clone of another one, in which case
refs/remotes/origin/HEAD is a symref.

Please note that this is already fixed in my strbuf patch for these files,
which had been applied in pu, but it seems to have disappeared from pu's
history. This also means the strbuf patch conflicts with this one. Please
tell me if you want a new strbuf patch made after this one.
