The hggroup object is used for things like stem plots.

I checked in the following change

  http://hg.savannah.gnu.org/hgweb/octave/rev/350148cc0774

It seems to work corrctly for me.

Could you please try it with 3.2.x and let us know if you see
problems?  If it works, then I suppose it would be OK to include with
a future 3.2.x release.
