Subject: expand_path and overlap

I'm wanting something similar to expand_path, but that will detect overlap.
So given this:

  expand_path("b/c/f", "/a/b/c/d/e") 

it would return:

  "/a/b/c/f"

expand_path currently returns:

  "/a/b/c/d/e/b/c/f"

No argument with expand_path -- a function that did what I wanted would not
allow a user to navigate to /a/b/c/d/e/b/c/f from /a/b/c/d/e without
specifying an absolute path ... but I think my version will suit my needs. 

So ... is there anything out there in Ruby land that does this already
before I build this myself?
