Details:

The changesets that introduced the --gui option no longer account for the
possibility of the user inadvertently running as a background process.  It
leaves an active zombie or daemon-like process running in the background that
affects future bash input:

Since the meaning of "run-octave" without option has changed from launching
the GUI--in which case "run-octave &" would be fine--this now has to be
addressed, likely in a way that the "run-octave --no-gui &" behaves:

at which point there may be a zombie still, but it stopped and not affecting
future keyboard input.
