Yes, according to the python docs that is correct. And that change fixes it
although it then breaks a stat test -- this patch fixes them both:

There is also a file_append function in main.py that opens files in text
mode -- but changing it to binary mode caused several tests to start
failing. I'm not sure if it should be changed and the tests fixed, or what
though.

Your change made the diff tests pass for me.

I think diffs have been created like this on Windows as long as I can
remember -- I guess I just assumed that for patches to be as cross platform
as possible, the line endings had to be LF. Would patch handle a CRLF hunk
from a Windows box sent to a Linux box (without any newline translation) on
a eol-style native file correctly? Is that an important use case?

It would be nice to fix the header inconsistency for sure, though. I think
that inconsistency causes some versions of patch to croak.

I think the blame test failure is related to it's use of file_append which
opens the file in text mode...I'm not sure, though, and I'm out of time at
the moment. I'll have to look at it next week if needed.

Thanks!
