Hmmm... that's strange. They should have changed (even if only slightly).

By default, the bgroup.inp script should select water molecules as groups.
Vis:

     b=(not (hydro or name Ca or name C or name N) and byres id $1 )

Of course, the type of refinement (group B or individual B) should
be determined by whether or nor free-R goes down.
