Yes, this was kind of bugging me, so here's a patch to reuse that logic
(it applies on top of yours).  While doing this I noticed that we
earlier missed that `*` is not considered isolated, unlike `?`.

Assuming no problems, I'll just push your two patches followed by mine
(I considered squashing, but probably that makes things harder to
follow in this case).
