[antlr-interest] Root node transformation

[Bryan Ewbank]

Hmm; that's funny.  There's reference in antlr.pdf on pg 122, but it's
only "#id"; rather than "##".  I think I picked that up from the
examples, or from the newsgroup... "##" means the same thing as
"#rulename" for any rule, and eliminates some cut-n-paste errors for
me.
