[antlr-interest] Get the line number in my deprecated messages

[Monty Zukowski]

Yeah, there's a getLine() or somesuch in the Token class.  If you're 
using a recent ANTLR then it will be filled in automatically as long as 
you call newline() in your lexer rule that matches newlines.  The java 
grammar is a good place to see how this works.
