I remember working on this and thinking that the rules for
overriding torsion parameters seemed wrong. As far as I can
remember, the parameters are merged (keeping non-overridden
multiplicities) rather than having all the ones from the 1st
parm.dat/frcmod deleted before adding the new ones. This is
a user interface issue, and I favor the delete-all-multiplicities-
then-add-new-ones approach.
There could be a bug too :-)
