It seems to be the case that if you type c-u c-@, then you have to
wait for the c-U to be displayed at the bottom of the screen before
typing the c-@, or else it (the c-@) is ignored.  This is not the case
for c-U in general (e.g. c-U c-B works fine).  I thought I was
hallucinating this for a long time, since it seems like such an odd
behavior, but I am pretty sure it is true.
