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
