Follow-up Comment #8:

This bug is still present in Octave 5.1 if the editor is emacs and is run in
"async" mode (the defaults for octave-cli users).

As discussed a while ago, the cleanest solution is probably to add a new
(possibly internal-use-only) way for Octave to create child processes such
that they are not bound to the terminal that Octave is running in and do not
receive the same signals that Octave does when running in a terminal
emulator.

For example, an easy workaround is setting the EDITOR environment variable to
"setsid emacs".

The attached patch adds a "detach" option to the 'system' function, I have not
reviewed it or tested it yet.
