No -- dot is the only character with position-specific rules,
and every other character in the forbidden set is rejected
anywhere in a component.

The file already exercises each of those rules on its own -- the
leading/trailing-dot, ".lock", empty-component, single-level and
--normalize cases are all present. So this isn't reaching for
exhaustiveness; the coverage was already broad, and this just
fills the untested gap -- of the "forbidden anywhere" characters,
only "?", "\" and ".." were tested embedded, so I folded the rest
into the loop.
