In measure@tie{}2, the staff labeled ``Test'' should change to 5/5 time and the
two staves grouped with it should change to 3/3 time.

In measure@tie{}3, the staff labeled ``Test'' should remain in 5/5 time (no new

time.

In measure@tie{}4, the staff labeled ``Test'' should revert to 1/1 time and the
two staves grouped with it should remain in 1/1 (no new time signature printed).

The two other staves should indicate 1/1 time from the start with no change at
any point."
