* parser.l (REGOP): New regex alias for matching all regex
special characters.
(grammar): Several rules for regex special characters merged
together. New rule introduced to match a special character
after a backslash, making it literal. The old rule which makes
literal any character after a backslash now throws an error,
unless version 105 comaptibility is selected.
