prompt_status does seem to be available in psql's MainLoop(), so I
think that could be done, but the problem is that I don't know exactly
what message would be useful to print when we're in a "in quotes"
state. If I had a good message text for that state, I might just
choose to use it always rather than multiplying the number of
messages.
More broadly, I think what is needed here is less C-fu than
English-fu. If we come up with something good, we can make it print
that thing.
