No, it most probably won't... You don't want to increment the line number on a 
tab (\t). And the action you put at the end is only called for \r because the 
parentheses are missing. Here's what I'm using:

protected
EOL : ( options { generateAmbigWarnings = false; }
    : "\r\n" 
    | '\r'
    | '\n' ) { newline(); } ;

I have no Token.SKIP in there because I use this protected rule in two other 
rules that already set the Token.SKIP type.

Cheers,
