Thank you very much!

The question is resolved: Earlier versions would, without
the little "extra-offset" tweak, print the slur in the
main staff, like attached acciacc-slur-lily-2.3.3.png.

The maintainer improved this by adding extra-offset, cf. attached
picture acciacc-slur-extra-lily-2.1.0.png.

(I could not experiment with the exact same version as
the maintainer has used, sorry!)

However, this leaves the question as how to distinguish the music
layout commands from "repair" additions (which at this time in
the history of the humanities' quest for beautiful musicprint
are quite natural.)

Thinking system-language: The Lilypond language must have
certain freedoms in order to calculate an appropriate layout.

Thinking practical: If the maintainer with reasonable confidence
can assume that certain direct manipulative assignment (tweaks)
are temporary, version-dependent adaptions, then he could mark 
those "tweaks" in some way; but which way?

P.S: The (chroot'ed) 2.3.3.hwn version 
complainted about missing fonts.

warning: can't find font: `ecrm6'
warning: Loading default font
etc.etc. for ecrm8, 10, 17, ecbx6, 8, 10, 12, 

but the transformation otherwise succeeds.

These fonts are not present in the newer version
2.4.0 installation either.
