Details:

The function edit() states that EDITOR defaults to the value of Octave's
EDITOR. However, changing its value after calling EDITOR the first time has no
effect.

Example:

octave:1> EDITOR
ans = emacs
octave:2> edit help
octave:3> sh: 1: emacs: not found

octave:3> EDITOR nano
octave:4> edit help
octave:5> sh: 1: emacs: not found


I can imagine that when using the function edit() for the first time,
non-emacs users will be caught by surprise. They would then try to change the
value of EDITOR and caught by surprise.

On a related note, conflicting documentation exists between EDITOR (which
suggests that is only used by edit_history) and edit (which says that uses
EDITOR as default).
