[antlr-interest] Multiple Lines with Implicit Endings in ANTLR

[consiliens at gmail.com]

I'm attempting to enhance a simple grammar to support entries longer 
than one line.  The Eclipse project with all the code is
http://tinyurl.com/yj62hqe
Using ANTLR and Eclipse was easy thanks to the excellent JavaDude 
screencasts[0].

Quiz.java correctly identifies the question (q), correct answer (c), and 
incorrect answer (i) for single line entries.

q : 1. hi
c : *a. hi
i : b. bye
q : 1. bye
i : a. hi
c : *b. bye

The quiz language is similar to grammars found in jbehave[1] and 
Gherkin[2][3].  In these grammars there are no explicit end keywords.  I 
also looked at the wiki example from tpdsl[4], however that fails on the 
most basic wiki input such as
* 1
* 2

MQuiz.g contains my failed attempt at using ideas from the Gherkin 
Ragel[5] grammar to support multiple lines.  Does anyone know how to 
support multiline properly in this grammar with ANTLR?

Thanks.
