Current branch: contextchange
Tracker issue: 5116 (https://sourceforge.net/p/testlilyissues/issues/5116/)
Rietveld issue: 322820043 (https://codereview.appspot.com/322820043)
Issue description:
  Allow \change to same context type  The \change command no longer
  refuses to change the parent of a context when the context itself
  would be of the proper type to change to.  This allows changing the
  parent of a context that could be nested, like StaffGroup in
  StaffGroup or NullVoice in Staff (since NullVoice is also aliased to
  Staff).

Could you rework your almost minimal example into a regtest?  Those give
me much more of a headache than most code changes since there is no
"obviously best" regtest to aim for.

Thanks
