Two fixes:

- Updated Selector.matches to come closer to the api the test suite is
  expecting. It's not actually the object that we want, but a list is
  enough to pass many of the tests which only care about the number of
  results.
- Fixed a bug involving the same variable name being used for two
  different things, which was causing bogus matches.
