[Octave-bug-tracker] [bug #46661] Disable Ctrl+D instantly closing GUI

[Mike Miller]

Follow-up Comment #6, bug #46661 (project octave):

It's actually not even interpreted by readline, it's at the terminal driver
level. The terminal settings interpret the Ctrl+D as an EOF character, and the
interpreter parser handles the EOF.

You can verify this by running octave with --no-line-editing and Ctrl+D still
works.

Also note that it's Ctrl+D only when the input line is empty. So we don't want
Octave to exit if I've typed some text and then hit Ctrl+D, that means
something else to readline (delete-char by default).

Now we could use some terminal control calls to disable EOF processing, but
that might break other things, for example I wonder if digging into that would
break how Octave works on file input.
