Follow-up Comment #8, bug #58944 (project octave):

Typo in the markup. Repeating the previous post:

There are currently several BISTs like the following ones in qr.cc where `a`
is dense:

%! [q,r,p] = qr (a, 0); t(j++) = __testqr (q, r, a, p);
%! [q,r,p] = qr (a',0); t(j++) = __testqr (q, r, a', p);


So is this an un-documented extension in Octave? Or should we also remove
these tests?
