Hmm...this may be more difficult than I thought.  Consider relative paths:

File.join(File.split("foo")) # "./foo"

Since "foo" and "./foo" are equivalent, I can't really complain here. 
Making this work so that it returned the orignal "foo" instead of 
"./foo" is too much work for too little gain I think.

I think I'll just drop it (on the *nix side, anyway), and let folks use 
Pathname if they really want hardcore pathname handling.
