[kelbt-users] [feature proposal] autocommit mode

[Elijah Epifanov]

There's no need to delay commit when parsing an unambiguous language,
therefore every rule will need (if efficiency is of concern) to commit
after reduce.

It would be convenient to set an auto-commit mode on on per-grammar
basis and (rarely, if at all) disable it for specific portions when
needed.
