- Added missing JRE 8 methods to "Pattern" for JRE 8-17 compatibility.
- Gave up on JRE 6 compatibility - minimum JRE verseion is now 8.
- Fixed some scanning rules in "comment mode".
- Catch infinite quantities of zero-width operand (creates an endless look otherwise).
- Fixed the backtracking of "\r\n" sequences (may pose two (!) line breaks!).
- Fixed allowed characters in capturing group names.
