scm/music-functions.scm:1784: (if (<= 2 (length stems))
Why not use "and" here and leave out the #f below?  Then one does not
hunt for #f to figure out what happens when the condition is false.

scm/music-functions.scm:1801: (let ((span (ly:engraver-make-grob trans
'Stem '())))
Why not have "root" as the cause, the last element of
ly:engraver-make-grob?  That would make the stem span tweakable.
