What does "path" mean in this context? How is it different from
%(refname)?
I found the answer below, but I could not guess from the doc and commit
message. Actually, I'm not sure %(path) is the right name. If you want
the "file/directory" analogy, then %(dirname) would be better.

This assumes you have two / in the fullrefname. It is normally the case,
but one can also create eg. refs/foo references. AFAIK, in this case sp
will be NULL, and you're then calling strchr(++NULL) which may segfault.

You should add eg.
git update-ref refs/foo HEAD
git update-ref refs/foodir/bar/boz HEAD
before the test to check and document the behavior for such refnames.
