[antlr-interest] newbie question, escaped characters

[Richard Clark]

This looks like ANTLR 2 code ("protected" instead of "fragment".) I
apologise for not seeing it earlier.

The default for ANTLR 2 is to not look ahead unless you ask it to. If
you're using ANTLR 2, try adding "k=2;" (without the quotes) in your
options.
