thanks for the suggestion. I guess i had found another way around the
problem as well. But i really wanted to match the line exactly and i
wanted to know why it doesn't work. That is less for the purpose of
getting the thing to work but more because it greatly annoys me off that
i can't figure out why it doesn't work. I.e. why the expression is not
matches {32} times. I just don't get it.

anyway, thanks though
