I also wanted to point out, but forgot, that this command is not really
creating a shell type -- it's creating a full-blown type, because there
are args.  Shell types are created when no args are given.  This happens
to fail due to the internal creation of the shell type because of the
failure to look up the i/o functions, but as far as I can see the
original code should fail in any type creation in pretty much the same
way (didn't actually test that); not completely sure why this wasn't
more visible in regression tests.

I simply removed the word "shell" in the provided test case in the
committed version, anyway.
