[antlr-interest] Lexer options in composite grammar

Hi,

is it possible to define lexer options in a composite grammar? I tried  
to find something about this in The Definite ANTLR Reference, but  
didn't succeed.

I'ld like to enable backtracking for the lexer, because currently the  
parser fails to distinguish between three keywords when two of them  
are together a prefix of the third one. I can imagine, that a lexer  
that does backtracking will solve this issue.

Regards,
Sebastian
