I have some custom code in my init directory that does something very
similar, and I've settled on adding `composition' to
`font-lock-extra-managed-props'. IIRC, the problem I was solving is that
otherwise removing a few chars from the composed symbol did not make it
un-composed.

Maybe we should make a font-lock-specific alias for `composition', like
`font-lock-face' is for `face', and use that.
