Details:

Running "test legend" with the graphics toolkit gnuplot fais with the
following error:

>> graphics_toolkit gnuplot
>> test legend
***** test
 hf = figure ("visible", "off");
 unwind_protect
   axes ();
   hplot = plot (rand (3));
   try
     legend (hplot, struct);
   catch
     [~, id] = lasterr ();
     assert (id, "Octave:invalid-fun-call");
   end_try_catch
 unwind_protect_cleanup
   close (hf);
 end_unwind_protect
!!!!! test failed
ASSERT errors for:  assert (id,"Octave:invalid-fun-call")

  Location  |  Observed  |  Expected  |  Reason
     []                   Octave:invalid-fun-call   Strings don't match


There also seem to be a few other cases where the error id has changed with
respect to the legacy legend function that is used for gnuplot.
