Thanks for this suggestion.  I am currently using Lilypond v. 2.19.48

Unfortunately, after trying this out, I find that changing the
StaffGrouper parameter values after the PianoStaff has been created
doesn't work.  I came across a similar problem once with, I think,
changing a Staff parameter.  The values seem to be built into to the
context on creation, and can't be altered later.

I'll probably have to add an invisible dynamic or something like that
to force the staves apart on the relevant lines of music.
