Even so, I had %option yylineno removed, also checking that line number
snippets were not invoked. And then, yylineno proved insignificant. Even
though I just timed it by hand, the sample was over about 600 lines of text.

It would probably be nice with a line counting method that does not have to
rescan the match. BTW, what happens if the match does not fit into the
buffer, which might happen if the comment is very long?
