I have modified the unique function to handle cellstr arrays with the rows
option. The modified function (see attachment) includes two extra BISTs for
the new functionality and a minor adjustment in the documentation regarding
the “rows” option. I have attached a patch file 'unique.diff'.

This is an Octave extension, since MATLAB does not support this functionality.
Another issue about MATLAB's unique implementation is that it does not allow a
combination of 'sorted'/'stable' and 'first'/'last' options. Octave behaves
the same. As a result, if we opt for 'first'/'last', these are always computed
with 'sorted' by default, which is a bit annoying since there are cases that
some extra flexibility would be very useful. Are we interested in obtaining
this extra functionality? If so, I could work on this and submit another
patch.
