Ack, we are foo-bar'ed!

Now I know why I avoided flex in PHP2...

with current %option yylineno:

> flex -p -p language-scanner.lex
%option yylineno entails a large performance penalty
-I (interactive) entails a minor performance penalty
REJECT entails a large performance penalty

Removing %option yylineno:

> flex -p -p language-scanner.lex
-I (interactive) entails a minor performance penalty


It looks like %option yylineno automatically means we need REJECT rules
turned on.  And having REJECT rules seems to mean that we cannot dynamically
grow the buffer for large input files?

Please tell me that I am somehow on the wrong track here.
