Hi Johannes,
I 'd like to propose the enhancement below to LilyPond. It will
increase the indent and short-indent of a score to fit all of its
instrument names and instrument short names.
This is a great idea (and a feature I've been missing for quite some time).
In the current version, subsequent systems get a positive short-indent
even if there is no shortInstrumentName given. Is that on purpose? I
would have expected a minimal
\version "2.22.0"
\new Staff { \repeat unfold 64 c'4 }
to yield the same result before and after your patch.
