2.9.14+ hold issue

[Fredrik Lingvall]

On the current CVS  (and gnuplot CVS),

octave:69> figure(2);
octave:70> clf;
octave:71>
octave:71> plot(Ro(:,1),Ro(:,3),'o');
octave:72> hold
warning: __plt_get_axis_arg__: some elements in list of return values 
are undefined
error: invalid conversion from matrix to real vector
error: get: expecting graphics handle as first argument
error: evaluating assignment expression near line 44, column 14
error: called from `hold' in file 
`/usr/local//share/octave/2.9.14+/m/plot/hold.m'
octave:72> plot(Ro_orig(:,1),Ro_orig(:,3),'r*');
octave:73>

If I add 'on' after hold then there is no problem but I think hold 
should default
to 'hold on' after a clf;
