Unfortunately, I think Emacs doesn't have a clear view about
how to handle an integer which contains a character code and
meta-modifier masks. Is it a character or not?
I think it's not a character but an event object, so the
above code should be:
(key-binding (vector last-command-char))
The related problem is when to change, for instance, (' ' |
CTRL_MASK) to '\0'. Now Emacs signals an error when we type
C-q C-SPC.
