Well...
There is no silver bullet here. In the original snippet I wrote, when two syllables \
are squashed, they would still be typeset separately, and then printed adjacently. \
Werner improved the snippet to make it typeset the two syllables together as a single \
run of text instead (with \concat), in order to enable font ligatures — and complex \
text layout, for languages where this is applicable — between the two syllables. \
But it might be fiddly, after making Pango lay out the combined text with ligatures, \
to extract back the parts. Off the top, I *think* it's possible (I'd have to check \
how to tell Pango to force an itemization boundary at a given point; I think it can \
do that, since it's also able to render arbitrary parts of the text in a different \
color), but I'm pretty sure it requires new C++ code.
In the very short term (i.e., what can we do in Scheme that works in 2.24), I'm \
afraid the only available improvement would be to make the whole syllable link back \
to one of the input syllables in the code, and giving up on having point-and-click \
separate the syllables.
By the way, this problem is more general, since it also affects properties like color \
and whiteout. (There's a reason it's in LSR and not in LilyPond proper yet.)
