I applied the patch and made a few additional changes.  Instead of
using a separate function for tests, we usually put the tests at the
end of the .m file.  For example, I added these lines based on your
test function:

  %!shared x, idx
  %! [x, idx] = sortrows ([1, 1; 1, 2; 3, 6; 2, 7], [1, -2]);
  %!assert (x, [1, 2; 1, 1; 2, 7; 3, 6]);
  %!assert (idx, [2; 1; 4; 3]);

We don't have a formal document yet.

It's a file containing diffs and some extra information for Mercurial
(hg) which is version control system we use for the Octave sources.
