If a filename in a git diff uses complex unicode characters (such as CJK),

instead of including those characters in the diff header, the utf-8 encoded

bytes will be escaped using a \decimal syntax. This syntax is really difficult

to disentangle on the server side without writing our own parser. Luckily, it's

pretty easy to turn off this quoting.

Created a file called "??\test" and ran rbt diff and rbt post. Saw that

the diff it was posting no longer included escaped bytes.
