Details:

This function:

----------
function func

addpath('/home/user/octave/test');

[folder,~,~]=fileparts(mfilename('fullpath'));
disp(folder)

end
------------
adds a path and displays the path the file func.m is in.
It works correctly when run from the command line. However, when invoked with
the run() command, it does neither and just exits. Worse, this seems to leave
Octave in some undefined state where running the function again from the
command line no longer works. This state is removed when 'clear all' is used.
I have had none of these problems with run() on Matlab.

The temporary fix appears to be to modify func.m so it is a script rather than
a function.
