This list is unnecessary, since the list is quoted, I think.

Perhaps for maximum clarity, we should write this as:

#(define-markup-command (fingernail layout props) ()
  (ly:make-stencil
   (list 'bezier-sandwich
         (list 1.6 1.5 0.4 1.5 0 0 2 0
                0.4 0.75 1.6 0.75 2 0 0 0)
         0.15)
   (cons 0  2)
   (cons 0  1.75)))


I think we just had a discussion where we decided that the '(A . B) syntax
was more confusing than (cons A B) because the period could be overlooked.

HTH,
