[antlr-interest] wildcard in tree grammar

[Terence Parr]

Hi gang, I've recently fixed how this wildcard thing works in tree  
grammars.

October 21, 2008
* Made . in tree grammar look like ^(. .*) to analysis, though ^(. foo)
   is illegal (can't have . at root). Wildcard is subtree or node.
   Fixed bugs:
     http://www.antlr.org:8888/browse/ANTLR-248
     http://www.antlr.org:8888/browse/ANTLR-344

Not sure why ^(. foo) is illegal...hmm...weird.
