Description

It turns out that difflib's unified diff implementation, while seemingly okay,
chokes pretty badly with files that don't end in newlines, or start with
byte-order markers. After piling workaround on top of workaround, I've decided
to rip it out and just use the diffutils diff command.

Testing Done

Posted some changes containing previously problematic files. Saw that they all
worked.

Shouldn't this use b'..'?	chipx86	June 25, 2015, 2:11 p.m.
What happens here if old_label and new_label are bytestrings, since they're then mixing with Unicode strings?	chipx86	June 25, 2015, 2:11 p.m.
Change this comment to reflect that we're no longer using difflib.	brennie	June 25, 2015, 2:21 p.m.
