Well, the proper way of doing it requires (I think) this
rather advanced \layout block:

  \layout {
    ragged-right = ##t
    \context {
      \RemoveEmptyStaffContext
      \override VerticalAxisGroup #'remove-first = ##t
    }
  }

I'd be surprised if anyone was okay with having that in the
LM, but in either case, what's there now needs to be removed
or replaced.  Of the two solutions presented, the nested
contexts in the first are too convoluted, and the method of
using two \score blocks (given in the second solution) is
semantically incorrect.

I've attached a solution here.  Have a look at it and let me
know what you think.
