[antlr-interest] Local backtracking

[Johannes Luber]

Hi!

I'm wondering how one does determine which rules have to receive
"options {backtrack=true;}" so the warning regarding non-LL(*) vanishes.
Applying it to the marked rule alone doesn't work and making it global
because of one rule alone I can't give a predicate (because I believe it
would exclude valid token streams, too) seems too much.
