Details:

In Octave 5.2 it is possible for the first argument to be a handle to an
existing legend object.  The second argument can then be other legend actions
such as "boxoff" or "hide".

This no longer works on the stable branch.  The error is obscure


error: legend: objects of type "axes" can't be labeled
error: called from
    legend>parse_opts at line 661 column 7
    legend at line 134 column 8
    tst_leg at line 7 column 1


, but apparently it is because the new code is only looking for an axes handle
in the first position.

Test code which is also attached as tst_leg.m is:


graphics_toolkit qt

hf = figure ();
hax1 = axes;
plot (hax1, 1:10, 'o-b');
hl1 = legend ("axes1 legend");
legend (hl1, 'boxoff')
