Well, it's not just about case sensitivity.  The comment for
SplitDirectoriesString points out that it deals with embedded spaces
differently, and it also applies canonicalize_path().  I'm too tired
to think hard about what that part might mean for compatibility, but
it probably isn't nothing.

Anyway, I agree that this is an appropriate change for HEAD.  Just
not convinced that we should shove it into minor releases.
