I changed it to use `error' instead.  The code isn't used unless the
user specifically asked for it, and it that case it might as well stop
if the user made an error.

Feel free to revert or change again.

Oh. But maybe that's bad for verification?  Yes.  I reverted it
partially, so now hashcash-generate-payment will throw an error if the
binary doesn't exist, while hashcash-check-payment will display a
message and sleep.

Feel free to revert or change again.
