[antlr-interest] Quoted String Literal - confused by greed=false behavior.

[G. Richard Bellamy]

I've got a lexer rule that should be gobbling everything after the 
double quote '"' except for the last double quote - I basically stole 
the rule from a post from Jim Idle 
(http://www.antlr.org/pipermail/antlr-interest/2010-March/038051.html).

I've also tried other variations on the same rule, and I'm a bit 
confused as it seems the {greedy=false;} option is being ignored.

Any help is appreciated
