I believe this should have gone to the user list as well so I'm
forwarding it there.

I see two issues here. The first is the inconsistent behavior. It
looks to me like the default behavior for a single was intentionally
changed for v2.19.83. However, the default behavior for multiple
staves remains unchanged.

The second issue is which behavior is "correct" and/or should be the
default. In my opinion, the default behavior for multiple staves
should have been changed as well, and the new time signature should be
announced in the second alternative as well as the first.

All the best,

Ralph
