'v' is called a 'kind-spec' in exuberant ctags/etags; the emacs
incarnations don't know about it and actually produce warnings.

As you are co-maintaining a fork of exuberant-ctags, I wonder if your
fork probably already knows about kind-specs.

Anyway, because of your question, I noticed some more problems with the
emacs part of tags.sh; patches coming shortly.
