This isn't particularly useful in and of itself, but it does introduce the
first (trivial) unit test, improves the documentation (including details
about how to debug init crashes), and made me aware of how unpleasant the
existing parser is.
I also fixed a bug in passing --- unless you thought the "peboot" and "pm"
commands were features...

Also switch the revision parsing over to sscanf as promised. I haven't
done the hardware parsing because I don't yet know whether we actually need
to keep the space-stripping code.
