patch attached.

Two points:
1. I have assigned my copyright for Emacs stuff to the FSF
2. My initial version of the patch was against bugfix and now I have set 
:package-version to "9.6"
     according to the instructions on the org-contribute page. I do not 
know if this is acceptable (it
     feels a bit like breaking the rules), but I am happy to redo the 
patch for main.

Best regards -- Gerard
