[antlr-interest] Support for .* tree rewrite rules

[Matthieu Riou]

Hi,

I've downloaded the latest version of ANTLR from Fisheye but I still can't
use AST rewrite rules for any lexer expression containing (.*). For example:

function:    'function' f=ID '(' ID? (',' ID)* ')' '{' (options
{greedy=false;} : .)* '}' -> ^(FUNCTION $f);

Anything like this will result in the following exception:

error(10):  internal error:

Any plan to fix this? Otherwise I'll have to do some manual heavy lifting on
the AST.

Thanks!
