Nope, sorry. I cannot accept this. This would be a new feature, and we
cannot implement new features until the sun goes super-nova. Sorry.

This is too cool. I never even knew this existed! :-)

I use the console quite a bit, too, but I do it 75% of the time because it
helps elide problems with gdb and insight getting out of sync.(Try up/down
in the console window. It doesn't work properly.)

I have one very little nit...

Could you change this to the "new" comment format? I know, this isn't
documented anywhere... I started doing this in regwin.it[hb] when I
tweaked the register window. I'm gonna try to stay consistent in its use
for new work. This'll help me track what has been touched recently and
what is still "legacy" code.

Something like:

# ------------------------------------------------------------------
#  NAME:         ConsoleWin::_operate_and_get_next
#  DESCRIPTION:  Invokes the current command and, if this
#                command came from the history, arrange for
#                the next history command to be inserted once this
#                command is finished.
#
#  ARGUMENTS:    None
#  RETURNS:      Nothing
# ------------------------------------------------------------------

Otherwise, APPROVED! :-) (Wow, a new feature. Where's my champagne?)

Now all we need to do is get ^R working...
