: Is this supposed to work with DOS-Paths and DOS-Drive-letters? 

It doesn't handle \ dirseparators, nor will it strip c:text.txt to
c: (doesn't recognize driveletter: as a separate entity in the path),
but the patch doesn't introduce this bug - the patch is just a
reorganization of the existing code that behaved exactly like that.
At least now there's only one place to insert a fix for this.
