That is a bug, I think.  I'll get back to you later after trying
reproduce it.

That is a typo, I think.  You mean [(control x) (control c)], which is
the normal binding of `save-buffers-kill-emacs', I suppose?  If so,
that is correct behavior.

`3' is an integer, which is mapped to a character according to the
ASCII table, ie, to ?\003, or control-C.  (Larger integers use an
Emacs-specific extension of the ASCII table.)  This is for
backward compatibility.

That is the correct syntax for characters.
