\left, \right, \up and \down?

[Mats Bengtsson]

Hi,

Why is it that
  \once \override Score.RehearsalMark #'self-alignment-X = #right
works well, whereas
  \once \override Score.RehearsalMark #'self-alignment-X = #left
produces the error
"type check for `self-alignment-X' failed; value `#<Music FingerEvent>'
must be of type `number'"

Similarly, #center and #up works as arguments, but #down fails.

It would be very convenient to have all these macros available and
it could be a clear improvement to the manual if they were used
consistently in all the examples and documentation instead of the
magic numbers +1/0/-1 used today.
