Using prefixcmp() instead of strncmp() there is what I meant by "fixing
the strncmp() at the beginning of do_one_ref()", so we are in agreement on
that point. What I found questionable was the removal of the trim
value. IOW, I would have expected the patch to be something like:

	if (prefixcmp(base, entry->name))
        	return 0; /* outside of our area -- ignore */
	... some other logic ...
        /* feed the callback, stripping the prefix */
        return fn(entry->name + trim, entry->sha1, entry->flag, cb_data);
