Dealing with readline makes it slightly more complicated than that,
because there is an intermingling issue with two independent output
streams.

In addition to a couple of well-placed fflush's, my hack around the
intermingling problem (which apparently only shows up when using the \o
option) was to throw a sleep(1) in before it sends the prompt
and queries the next line from the terminal, to give things a chance
to finish, but I don't know if that is a production-quality fix.
(I did find a couple of other examples in the code of a sleep() thrown
in apparently to resolve timing issues.)

I can take out the code I added to echo the command to the \o stream,
since that is a feature that I would probably want to amplify upon anyway.

If the team would accept the rest as a bugfix, I can send it.  Otherwise,
I'll wait for 7.5 and see if I can change the whole output section to
eliminate the problem completely.
