I'm not 100% sure either.

We could have a more complicated patch that arranges for do_displays to
be called just once, no matter what decision is made.  Maybe this would
be better?

I originally thought it was somewhat odd to deal with displays in an MI
stepping situation -- MI clients presumably would use varobj.  But,
really the scenario is that the MI client provides a console, the user
types "display ...", and then debugs some more.  I suppose the way that
the "next" is done wouldn't matter to the user?
