[antlr-interest] antlr & pipe

[Richard Clark]

My trick is to create a new TokenSource wrapping the original source that
always returns EOF for any attempt to read past the end. That way, if the
parser runs out of input tokens (and more can't be had from the tokenizer),
the parser will get an EOF.
