[antlr-interest] getting the correct line # from an exception

Dear Friends,

When my grammar contains an illegal token an exception is properly thrown
The exceptions message seems to always indicate the line # as being "1"
which is sorta useless when it comes to debugging,

My grammar indicates that "\n\r" should be skipped by the lexer, should I
increment something each time "\n\r" is encountered so that the exception
translates to the correct line?

Thank You Very Much,
Mark F.
