Nice!  I can see where this has its weaknesses too: it wouldn’t work if
the two chords weren’t approximately at the same height, but it’s
perfect for this case.  Thank you.

(Now I have to make an editorial decision whether to keep this, or to
use standard LilyPond chord slurs––i.e., just one single slur curve––and
be consistent throughout the project.)

Question about the code, though:  I can kinda-sorta follow what it’s
doing, or at least I can figure out where in the reference manual to
look up the details.  But whence the numbers 0, 1, 2.4, & 3.7?  Are
these trial-and-error numbers?
