While Chandler seems to have understood the idea, I'm still slightly
confused in what the test would look like - perhaps I need to see
it... :)

Also, I think this would test that the mechanism for setting adjusters
works - in my opinion it's more important to have a smoke test for the
syntax-only default case first (which will not ensure that we're able
to change the adjuster, but that the default adjuster works the way we
want it to).

That is, while I think more specific tests are valuable and adding
them will make me happy, I'd try to come up with a test that checks
the current fsyntax-only behavior first.
