But this is not that easy with uuencoded files, either - I'd just end
up uudecoding both files before running cmp -x. And for the case under
discussion here (firmware files) we treat them as opaque binary
objects; comparing them is generally not interesting anyway.

We have bsdiff and bspatch, but their output is not designed for human
consumption or editing.
