So there is another way? Mere (load "/tmp/lisp/fontset.el") have no use after built-in ‘fontset’ is already loaded of course. I’m just curious.

Okay, if I can’t, I can’t. As for ‘prepend’ it actually works all three ways for me: obviously ‘nil’ (for override, not what I want), ‘prepend’ (as expected) and ‘append’ (no idea why).
