You need before-line-breaking here so you can use the function
ly:item-break-dir:
\override Clef.before-line-breaking =
#(lambda (grob)
(if (equal? (ly:item-break-dir grob) LEFT)
(ly:grob-set-property! grob 'stencil
(lambda (grobb)
(grob-interpret-markup grobb
#{ \markup \translate #'(0 . 2) \flip \musicglyph
#"clefs.G" #})))))
I added the translate in the markup to bring the clef to the correct
vertical position.
