Hmm. Right. I failed in the error-prone reverse-engineering of the code.
I now see that _roots() also returns exact matches and that .exact()
also returns roots (when .anypats() is true).
.exact() can thus only be used after checking that .matchfn matches and
that it not just is a root, and .files() can also contain both files and
I think that the thing that initially led me in the wrong direction was
that .files() can contain the same root multiple times and thus in some
cases would walk the same tree multiple times.
I will revisit later.
