Normalize to "foo/bar/" so that it still forces to resolve symlinks and 
yield a directory.  For example, lstat(), -- you can see the difference 
by shell `stat foo/bar/` and `stat foo/bar` when bar is a symlink -- or 
unlink()/rm.  (Or when bar is a plain non-directory file: 
slash-->deserved error.)  I'm not aware that removing the dot itself has 
any effect here, though. (counterexamples welcome).
