8b5b007a51 We want to cover the marked version of the identifier (which has the proper 
value), not the "regular" version that's now a transformer to a contracted
version of the marked identifier (and thus double-contracting here).

5b9f0aa322 Implemented a `no-empty-edge-matches' function using the new 
`make-regexp-tweaker', which produces a regexp that cannot match an
empty string at the beginning or the end of the input.  This:
* simplies a whole bunch of messy and fragile code
* makes `regexp-split' and friends usable with a pattern like #px"\\b"
  (which previously would match in every position, making it explode
  the string to 1-character strings)
* makes it even closer to what perl does, the only way that we produce
  a different result from perl now is that we don't blindly drop empty
  matches at the end like perl (it *does* keep empty matches in the
  beginning though)
The two tests that demonstrated the difference are now changed, and a
bunch of other tests added.
