[antlr-interest] Newbie Alert! Disabling the removal of whitespace in a rule

Hello folks,

I'm a newbie to Antlr, and I'm still trying to understand a lot of the 
basics... I hope you'll bear with me!

I have a rule as follows

	:	(.)* {greedy=false;};

It works OK, except for all the whitespace that is chopped off, 
resulting in a lot of tokens underneath sh_code_blob in the 
interpreter's tree. I'd like to have code blobs as one token.

Is there an option we can put (like the greedy above) that allows to 
disable the lexer's removal of white space? What other ways can I 
achieve my objective?

Thanks a lot!
