REVISION SUMMARY
  Motivated by incorrect regular expressions of the form [a-zA-z] or [a-Z], this patch extends the highlighting indexer to check for this kind of errors. This, however, is only a heuristic, so theoretically, we may have false positives. This is not an issue so far, though. In fact, this check detects two more issues, which are fixed with this change as well.

TEST PLAN
  make test
