Ah, sorry, I missed the fact that you were iterating over characters
instead of lines. 10 == ?\n. Gotcha.

But isn't that different than the original functionality? He
originally wanted a warning (specifically assert_equal as part of
Test::Unit) for each line that differed. Your code will only match the
first such case then break out of the loop.
