#44334: octave @3.8.1: Cursor keys and command line history not working in the GUI
------------------------------+--------------------------------

     Type:  defect            |     Status:  new
 Priority:  Normal            |  Milestone:
Component:  ports             |    Version:  2.3.1
 Keywords:  gui readline      |       Port:  octave
------------------------------+--------------------------------
 I have the octave port @3.8.1 installed in the +gui variant to try the new
 GUI. The GUI works quite well except for the editing shortcuts in the
 command line window: No cursor keys are working, i.e., editing the current
 command line has to be done only using backspace and delete. A command
 from the history has to be done using the mouse. I suspect something goes
 wrong with loading the readline configuration. Unfortunately, loading
 explicitly a minimal ~/.inputrc using readline_read_init_file() does not
 help. When the GUI starts up, the command line window contains the
 following messages:

 {{{

 The editing shortcuts work correctly in the command-line version of
 octave.

 I'm using an up-to-date MacPorts installation on OS X 10.8.5.
