Hmm, actually, there's something seriously screwy with the testrunner
at the moment: we don't actually support not and count, but tests
using them still manage to pass.  I was just experimenting a bit with
not creating .script files, and somehow reading the commands from
stdin changes the relevant behavior.  (The other issue with reading
the commands from stdin is that it appears to trigger some sort of
thread safety bug, but that isn't really relevant if you're planning
on rewriting the code.)
