Thanks.

While you're not exactly fixing a bug, this would benefit from a
testcase.

Just so that people do not misunderstand.  A test is _not_ about proving
that your patch fixed a bug.  It instead is to protect your change from
future breakages by _other people_.

Having a test that would fail if careless others muck with related
codepath in the future without taking your change into account is a good
way to make sure your new feature or your good change of behaviour keep
working (the alternative is for you as the author of such a valuable
change to stay on the list 24/7, audit all the patches that may negatively
affect your change and veto them before they are applied, which is
impractical for most people).
