New directive
%token_size_limit <limit>
where <limit> is a Java number literal or qualified identifier provides
an optional hard limit on token length.
The scanner buffer will not be increased beyond this length limit and
if a longer token is encountered the scanner with throw an EOFException.
This is for applications that require memory limits when parsing
untrusted input.
