[antlr-interest] Accessing the input stream from displayRecognitionError

[Gioele Barabucci]

Is it possible to access the input char stream from lexer's
displayRecognitionError(String[] tokenNames, RecognitionException e)?

Following the error chapter on the ANTLR book I managed to get Token names
and other grammar information. Yet, I don't see how to access the input char
stream to display the characters preceding and following the error.
