"loose ends".
commit fb79cea8ec10ebc40b96a05bf7f643e47fd93ddd

Issue 4324: Don't create Bottom to announce TimeSignatureEvent
As a fallout of issue 4138, << \time 3/4 \new Staff c2. >> created a
spurious Staff only containing a time signature. This change avoids the
creation of a Bottom context just for accommodating \time. As a result,
{ \tweak color #red \time 3/4 c2. }
will no longer show a change in color since no Staff context exists at
the time \time is executed and consequently the tweak does not apply
anywhere. You have to use \time in existing Staff contexts to have
either \tweak and point&click have an effect (and get an error locator
when something with typesetting the signature goes wrong). Outside of
such contexts, \time just changes properties of the Timing context.
So (after this change, or before the mentioned issue 4138) the gist is
that \time changes properties in the Timing context (which by default is
aliased to Score, thus not causing a Staff to be created) while \key
changes properties at Staff level which necessarily requires a Staff to
be created (unless already in existence).
