Failure to echo after numeric argument.

The following seems to be a relatively recently introduced bug in CVS
Emacs.  I believe I would have noticed it before if it would have been
there for a long time.  It does definitely not occur in 21.2.90.

Do emacs-21.3.50 -q --no-site-file --eval '(blink-cursor-mode 0)'

C-u C-x

C-u appears, C-x not.  It has been read OK though because a second C-x

exchange-point-and-mark: No mark set in this buffer

as expected.

M-2 C-c

No C-c to be seen.  This is especially dangerous, since a second C-c
out of confusion has, in many modes, the meaning of executing
something, which the user may not have intended to.

I have the impression (although I am not certain) that the bug is in
the C code.  While I know C, I am not really familiar with Emacs' C
code, making it difficult for me to debug this myself.
