Actually, I am doing that. I instantiate a CommonToken and call
setLine on it. I have used CommonToken::getLine inside the scanner to
confirm that the value in the Token is correct. This value doesn't
appear to have any effect on the line number returned in parser error

Meaning I could derive from CharScanner and just override nextToken as
I do now, but call newline instead of (in addition to?) setting
this information directly on the Token?

The source code for my scanner is included inline in my ANTLR grammar,
which an be viewed here:
