Before the previous commit, `for_each_bad_bisect_ref()` called
`for_each_fullref_in_submodule()` in such a way as to trim the whole
refname away. This is a questionable use of the API, but is not ipso
facto dangerous, so tolerate it in case there are other callers
relying on this behavior. But continue to refuse to trim *more*
characters than the refname contains, as that really makes no sense.
