Comment #10 on issue 1263 by [email protected]: MetronomeMark can not be
aligned on note if MMR in another voice
http://code.google.com/p/lilypond/issues/detail?id=1263
In key-clefs.ly, the tempo marks slide to the right of the key change
Those tempo marks are not the point of that regression test, merely labels
to describe how the key signature should look. They happen to be tempo
changes with /only/ a multi-measure rest in the measure---no notes in any
lower staves.
Where should the tempo go in that case? The books I have (Ross, Stone) do
not specify.
In the patch for issue 684, Neil gave his thoughts

-) A metronome mark at a full-bar rest should be aligned with the barline
instead of the paper column to the left of the rest.
-) If there's a tempo change at a key signature, the metronome mark
shouldn't be aligned with the following note.
(Both differ with what I am used to seeing.)
If we want the tempo marks over the first note if there is one, but over
the bar-line if there is /only/ a full-measure rest,
