[antlr-interest] moan

[Terence Parr]

Howdy.  greedy is still there.  Perhaps you didn't look at the right 
doc or something...pops right out at you:

http://www.antlr.org/doc/lexer.html#Greedy_Subrules

The various "shut off warnings" are useful for telling antlr a 
particular situation is cool.

#pragma appox was something else entirely, but had the *side* effect of 
generateAmbigWarnings=false.

Hope that helps,
Ter
