The other Up/Down commands use Neutral for the \revert.  Granted,
in this case you generally don't have lilypond choosing which
direction to place these objects, but I think it's still worth
following that standard.

Same as above.

These are fine.

Are these really so important to the notation that we need
predefined commands for them?  How often do people want to change
the default Alterations/Plus placement?  These might be better
just shown with snippets.

* note that I know little about figured bass.
