The bug comes from the fact that all :X path modifiers rely on
facilities which first parse the path by separating out directory,
basename, extension, etc., and then reconstitute the unchanged parts,
inserting PATHSEP where neccessary.

That means foo/bar/baz.x becomes more like

directory: foo/bar
basename: baz
extension: x

If you strip the extension, say, it puts the first two parts back
together as:

foo/bar\baz

using the platform path separator.
