Welcome to the Emacs shell

~/wip/emacs $ echo ${echo hi}
hi
~/wip/emacs $ echo ${*echo hi}
hi
~/wip/emacs $ *echo ${echo hi}
hi
~/wip/emacs $ *echo ${*echo hi}
hi
~/wip/emacs $

And the test seem to be pasing now?  So let's hope that it wasn't
intermittent (I tried 5 times for good measure), and close the bug.
I'll re-open if it happens again.
