Sorry for the confusion.  Step 2 was only meant to demonstrate the usual
echoing of prefix arguments; it's not a necessary step to get the bug.
Step 3 is really the entire recipe: after setting the mark (in any way)
and then typing M-w, all subsequent interactively typed prefix arguments
are no longer echoed.  (Under conditions I haven't yet been able to
determine, the echoing sometimes returns after a while, but immediately
vanishes again upon typing M-w (if the mark is set).)
