Yes, that magic is hardcoded in keymap.c (mostly in access_keymap
and Fdefine_key).  Note that it does not apply to Meta + function key,
so ESC a == M-a but M-f8 != ESC f8.

I think it would be interesting to make this less hard-coded and
generalize it so that other modifiers can be mapped to prefixes.
