... which may make the "call name_rev with this abbreviated path"
logic look something like this:
if (o && o->type == OBJ_COMMIT) {
if (can_abbreviate_output)
path = shorten_unambiguous_ref(path, 0);
else if (!prefixcmp(path, "refs/heads/"))
path = path + 11;
else if (data->tags_only
&& data->name_only
&& !prefixcmp(path, "refs/tags/"))
path = path + 10;
else if (!prefixcmp(path, "refs/"))
path = path + 5;
name_rev((struct commit *) o, xstrdup(path), 0, 0, deref);
}
