I think that's because your emoji.el isn't byte-compiled? Hm... mine's
not byte-compiled either? Do we have to add some incantation somewhere
to get newly-added .el files to be byte-compiled?

Yes.

C-h f will say that about all uncompiled functions that use lexical
binding, I think? So there's nothing special about it. (If it didn't
use lexical binding it'd say "lambda" instead of "closure", I guess.)
I have no opinion on whether this distinction (lambda/closure) is
meaningful to expose to the user in `C-h f'.
