Summary: mahalanobis is wrong (and probably belongs to the
statistics package)

_______________________________________________________
Details:
The function mahalanobis doesn't seem to work at all (note that it should
return one value for each row of X).
octave> X = rand (10, 2);
octave> Y = rand (4, 2);
octave> mahalanobis (X, Y)
ans = 2.6666
I'm unsure since when it stopped working but the 7 tests it has, only check
that it returns an error when input is complete garbage.
In a separate note, this function actually belongs to the statistics package
named mahal.
