Hmm. The loop grabs everything under refs/remotes/$that_remote/ and runs
"update-ref -d" on them.
I somehow had an impression that --no-deref option to update-ref was
invented to allow operating on the symbolic ref itself, instead of
operating on the ref it points at, but it does not seem to work.
I think "update-ref -d" should remove the ref without dereferencing
anyway. How about not doing your patch at all (you would need to manually
remove the symref in "prune" codepath as well), and instead doing this?
I do not know how this reacts when the tracked HEAD points at a ref that
lexicographically sorts earlier, say branch "A".

delete_ref(): when symref is given, delete it, not the underlying ref.
Removing the underlying ref without touching the symref does not make any
sense. An alternative would be to remove the symref _and_ the underlying
ref, but this should do for now.
