Details:

There is a small difference between Matlab and Octave regarding the return
value of the String property of a uicontrol widget:


in = { 'a|b|c', ['a';'b';'c'], {'a','b','c'}, ["a","b","c"]};
for i=1:numel(in)
  U = uicontrol ('Style', 'listbox', 'String', in{i});
  get (U, 'String')
end


Matlab returns:


ans =
  3x1 char array
    'a'
    'b'
    'c'
ans =
  3x1 char array
    'a'
    'b'
    'c'
ans =
  3x1 cell array
    {'a'}
    {'b'}
    {'c'}
ans =
  3x1 cell array
    {'a'}
    {'b'}
    {'c'}


Octave returns 'a|b|c' for the first two and does not yet understand string
vectors. Compatibility would be achieved by returning char arrays instead of
pipe-separated char vectors.
