Like Andrew I'd rather keep this in standard bencode if we possibly
can, though I would like to look at using bencode differently by
storing the standard core fields as a list rather than a dict.  (I
don't know if you already tried that.)  I'm a bit wary that if we use
fixed-width prefixes we'll either find someone wants to store a photo
of their cat in a revprop, or that we waste space serializing 00000008
on every string.
