Follow-up Comment #1:
I also glanced at the forum discussion last week. I have no problem with the
proposed change, but I doubt it will fix anything for a great number of
users.
I assume you are referring to the GLib g_spawn family of functions? In
particular, those functions set stdin to /dev/null by default, unless the
users chooses for the child to inherit stdin or to receive a fifo as stdin. I
assume most window managers and desktop environments execute launchers with
stdin set to /dev/null, which will still be considered by Octave to be an
empty file input, not a closed file descriptor. But I have not tested every
windowing environment to verify this.
The surest solution is to continue to use --force-gui when intending to run
Octave's GUI.
But like I said at the start, I have no problem with the proposed change. The
only way I know how to test whether this change will work is to run
$ octave ## start GUI, stdin is a tty
$ octave <&- ## start GUI, stdin is closed
$ octave </dev/null ## exit with success, stdin is empty file
