Sam Harwell f4a3d6f3a8 Move initialization of finallyAction to fillNamedActions - factory cannot provide context information for the Action construction before the constructor completes 2012-10-26 15:46:22 -05:00
Sam Harwell e89807e350 Add non-greedy quantifier syntax: greedy forms are *, +, ?, and non-greedy forms are *?, +?, ?? 
"greedy" is no longer a block option, and all loops are greedy unless the non-greedy quantifier is explicitly used
Add warning 131 when .* is used, because they probably intended to use the non-greedy form .*?
