XRegExp 3.1.0-next: completed changes

The following changes have been completed and are available via the latest build here on GitHub:

  • Fine tuning: Include lookbehind prefixes (?<= and (?<! in list of native tokens, to avoid splitting up this prefix in any custom addons.
  • Fine tuning: Remove repeated empty groups in generated native regex patterns.
  • Fix: Avoid runaway backtracking with very bad performance during first-time compilation of some regexes that use whitespace or comments with the x flag. (#129)
