lpeg and terminology

Hi list,
I'm brushing up on LPEG, trying some things out and wrapping my head
around this whole thing.  I'm currently going through the docs and "A
Text Pattern-Matching Tool based on Parsing Expression Grammars"
paper.  What's tripping me up is some of the terminology that's
currently a bit fuzzy to me.  If there's a good resource for getting a
handle on the basic, terminology-wise, I'd love to know about it.

Specifically, what does a phrase like "blind greedy repetition" mean?
I understand greedy to mean look for a mach until there are no more,
but blind is a bit of mystery.  Any info appreciated.
thanks,
wes
