ccc depends on facemenu, yet ccc doesn't stipulate facemenu as a dependency.

That's why I have to load facemenu manually before loading ddskk in emacs init file.

With package.el, facemenu was somehow loaded automatically. With elpaca, facemenu is not loaded automatically.

Error in post-command-hook (ccc-update-buffer-local-frame-params): (void-function facemenu-color-equal)

Okay, this was fixed.
