Just back from vacations, reading up the mails...
I tested the code below with 2.16.2 and 2.19.44 and colored the ref-points.
Images attached. Up to now they are simple observations, have to think
about further implications...
\relative d' {
\stemUp
\textLengthOn
\set Staff.instrumentName = #(lilypond-version)
d2^"foo"
d'^"foo"
d,^\markup \raise #4 "foo"
d'^\markup \raise #4 "foo"
d,^\markup { \null \raise #4 "foo" }
d'^\markup { \null \raise #4 "foo" }
d,^\markup \box \raise #4 "foo"
d'^\markup \box \raise #4 "foo"
d,^\markup \box { \null \raise #4 "foo" }
d'^\markup \box { \null \raise #4 "foo" }
d,^\markup \box \line { \null \raise #4 "foo" }
d'^\markup \box \line { \null \raise #4 "foo" }
}
Cheers,
Harm
