Comment #7 on issue 1150 by x.scheuer: RehearsalMark at start of line  
should not be printed above the clef
http://code.google.com/p/lilypond/issues/detail?id=1150

Anyway, can't we use Neil's

  RehearsalMark #'X-offset = #shift-right-at-line-begin

or

  RehearsalMark #'after-line-breaking =
#(lambda (grob)
    ;; apply shift
    (shift-right-at-line-begin grob)
    ;; call default callback
    (ly:side-position-interface::move-to-extremal-staff grob))

as a solution (at least temporary)?

It is indeed better than current behaviour, although there is no clear
"solid reference" or "common practice", as pointed by Reinhold's list
(BTW thank you Reinhold).

Cheers,
