Actually, the function is an abstract of a larger one, trying to achieve a) combination and alignment of various markups and/or \mark\default without disturbing a markFormatter. b) the possibility to stack the markups vertical or horizontal. c) different marks at line-end and line-begin with individual alignment. It was the attempt to get an alternative to Neil's multi-mark-engraver http://old.nabble.com/Nice-workaround-for-simultaneous-rehearsal-marks-%E2%80%93-thanks-Neil!-td32212763.html without the necessity to rearrange engravers. Well, in the end I puzzled myself by trying to deal with too many variables. Until now I couldn't motivate myself to clean up/improve the code to get a really working function. Perhaps I should return to it. ;) ... after finishing some other work I promised to do ...

Hi Jim,
below some code, which should do what you want.
Usage:
a)
Predefine two markups:
mrkpI = \markup \fontsize #-1 "to Coda"
mrkpII = \markup \fontsize #-1 { \musicglyph #"scripts.coda" }
b)
Combine and align them with `alignCombinedRehearsalMarks´. Use an alist:
myMarkI =
\alignCombinedRehearsalMarks \mrkpI \mrkpII
#`(;(center-on-first . #t)
(center-on-second . #t)
;(general-align . ,LEFT)
(outside-staff-priority . 5)
(break-visibility . ,begin-of-line-invisible)
)
This alist offers the possibilities to have the RehearsalMark centered
at the first markup or the second markup or align it as you want as a
whole. Please make one choice.
In addition you may want to set outside-staff-priority and
break-visibility within this alist.
Comment what you don't need, choose the values you want. Even an empty
list will combine the two markups, defaulting all other properties.
Some more comments in the code.
The Code:
\version "2.16.2"
alignCombinedRehearsalMarks =
#(define-music-function (parser location mrkp-1 mrkp-2 align)
(markup? markup? list?)
#{
%% Combines and aligns two markups
\once \override Score.RehearsalMark #'before-line-breaking =
#(lambda (grob)
(let* (;; mrkp-stils
(mrkp-1-stil (grob-interpret-markup grob mrkp-1))
(mrkp-2-stil (grob-interpret-markup grob mrkp-2))
;; x-extent of mrkp-stils
(mrkp-1-x-length
(interval-length (ly:stencil-extent mrkp-1-stil X)))
(mrkp-2-x-length
(interval-length (ly:stencil-extent mrkp-2-stil X)))
;; get alist-values
(general-align (assoc-ref align 'general-align))
(center-on-first (assoc-ref align 'center-on-first))
(center-on-second (assoc-ref align 'center-on-second))
(padding 0.6)
;; combine mrkp-1-stil and mrkp-2-stil
(combined-stil
(ly:stencil-combine-at-edge
(ly:stencil-aligned-to
mrkp-1-stil
Y
CENTER)
X
RIGHT
(ly:stencil-aligned-to
mrkp-2-stil
Y
CENTER)
padding))
(combined-stil-length
(interval-length (ly:stencil-extent combined-stil X)))
(set-stencil!
(ly:grob-set-property! grob 'stencil combined-stil))
align the stencil,
defined for:
;; center the new stencil on the first markup
;; for all not #f values.
;; (center-on-first . #t)
;; center the new stencil on the second markup
;; for all

the \hspace before and after the glyph are only to compensate for the
(missing in the 1st case) gap between the glyph and the preceding/following
text - they should only be adapted if you're changing the \fontsize and
\magnify the glyph (this is also the way to solve your 3rd question)

maybe it's a hack but it will do for many cases:
- add the text after the glyph as well, but hide it,
- correct the horizontal space before and after the glyph
- make sure the horizontal self alignment of the rehearsal mark is center
it should be possible to write a small scheme function to avoid having to
type the same text twice or to calculate the length of the text in another
way.
\once \override Score.RehearsalMark #'self-alignment-X = #center % default
\mark \markup {
"to coda"
\hspace #1
\raise #1 \musicglyph #"scripts.coda"
\hspace #-.5
\with-color #white
"to coda"
}
