Sending a fix is a good thing, but whenever doing one, could
people please also do a testcase that demonstrates the original
bug, and also a demonstration that the fix does not introduce
regression?
For this one, obviously a test for push that uses such wildcard
ref is needed but at the same time we would want a test for push
that does _not_ use a wildcard, fetch that uses a wildcard, and
a fetch that does not use a wildcard.
