Hrm. Do we want to make these workarounds work correctly? Or is the
final solution going to be that the first command you gave simply works,
and no workarounds are needed.  If the latter, I wonder if we want to be
adding tests for the workarounds in the first place.

I'm not clear on the expected endgame.
