Follow-up Comment #5, bug #41546 (project octave):

Given that diagonal matrices are already going to be very fast to invert, just
a for loop over the elements along the diagonal and a simple division
operation, I think it is okay to have an extra explicit test for the element
being zero and keep compatibility with the regular pinv.

I made that change in this changeset
(http://hg.savannah.gnu.org/hgweb/octave/rev/16b0cd465ecd).
