From user perspective, yes.

Ideally yes, agreed.

This tentative patch fixes both cases, by limiting the fix of commit
3a87ae656c28 "Use console uiout when executing breakpoint commands" to
the case for which the corresponding problem was reported: INTERP_MI. [

At this point I don't understand yet why special-casing INTERP_MI would
be the correct thing to do here.
