The mark does not use much trickery, it is in concept part of the
column of bar lines, and the extra-spacing-* settings define how much
space the mark gets to the other columns, whether these columns
contain notes or bar line.
Unfortunately RehearsalMark spacing has a few small bugs, such as
forgetting its space reservation after a couple columns of notes have
gone by. Probably, though, something along these lines will work for
you. You can treat special cases with \once\override...
\relative c' {
\override Score . RehearsalMark #'self-alignment-X = #LEFT
\override Score . RehearsalMark #'extra-spacing-width = #'(-1 . 0)
%% Shift the space-reservation vertically up, to clear the stems
%% (stems get space reserved to the top of the staff in ver 2.12)
\override Score . RehearsalMark #'extra-spacing-height = #'(3 . 3)
%% Make bar lines taller than (most) stems
\override Score . BarLine #'extra-spacing-height = #'(0 . +3)
R1
\mark \markup "foo foo foo bar"
c1
\mark \markup "foo foo foo bar"
c4 d e f
c4 d e f
}
%% Enable drawing of spacing outlines
\layout { \context { \Score
\override NonMusicalPaperColumn #'stencil = #ly:separation-item::print
\override PaperColumn #'stencil = #ly:separation-item::print
}} #(ly:set-option 'debug-skylines)
