So arguably maybe we should have turned that patch into a binary patch, 
but then it would have been really hard to read, and GNU patch and friends 
couldn't have read it.

So I think a better option would be:

You have an alternate fix, namely to only look at the NUL character at 
newline boundaries. Also, when it comes to "git log", you actually know 
even more: each commit begins with "commit".

A patch will always be nicely line-oriented, and will never have a NULL at 
the *beginning* of a line.

So you could actually make the parsing really strict, and look for the 
sequence

	'\n\0commit '

and that's a very trustworthy delimeter.

But yes, you can have NUL-characters in the middle of patches.
