Indeed, that does seem a little clumsy to me, too. It's kind of a great
hack, but I could foresee functionality like '--no-symbolic' to be
useful to avoid hackery like this.

Yep. It's good that your patches are mainly in the 'ref-filter.[ch]'
code, so it would be easy to wire up new flags in both the branch+tag
builtins, too, since they use the same ref-filter API.
