Headers output separate from their diff...

[wesalvaro]

moving the print out into the diff header line case (out of the else) fixed it for the most part.

Do you have an example of what you would except vs. what you got?

I don't have any handy, but it was like this:

=== FILENAME_A
=== FILENAME_B
DIFF_A
DIFF_A
DIFF_A
DIFF_B
DIFF_B
DIFF_B

That kind of thing.

~~Seems to work as long as there is only one file changed.~~ Works for more complex diffs, even if more than one file is changed.
