If I want to offset a `\tempo` mark horizontally, only
\override Score.MetronomeMark.X-offset = #3
\tempo ...
works. Writing
\tweak MetronomeMark.X-offset #3 \tempo ...
has no effect. I now wonder whether it would be possible to extend
the `\tweak` command to accept also the context:
\tweak Score.MetronomeMark.X-offset #3 \tempo ...
In case this isn't possible it would be nice to document it in the NR
sections about `\tweak` and `\override`– only stems, automatic beams,
accidentals, clefs, and time signatures are mentioned as not working
with `\tweak`.
