You cannot 'fix' the ones deployed in the wild, but I think saying
"funny ref" and not aborting is a good compromise.  The updated
documentation for bundle can mention that error message and explain
that the older version of "clone" will say that in what situation.

I didn't notice it the first time, but I think the above would read
better and match what has been discussed on the on-the-wire format
to swap the order, i.e. use "HEAD:refs/heads/Test" to mean "HEAD is
a symref that points at the Test branch".

Yes, that is a sensible check.
