ARGH!

You are of course correct.  Sort of.  See, the "-c bash" isn't really a
su argument; it's being passed to the shell.

On consideration, it's obvious that this has to be the case, because otherwise
you'd be able to override an account's shell (say, an account that
intentionally has nologin as a shell).
