I don't want to set multiple marks in the same position though.  I just
want to be able to know in which buffer I most recently set a mark.  I
expected that the first element in global-mark-ring would tell me, but it
doesn't, not reliably, because if the mark already happens to be at the
place I run set-mark-command, the ring is not updated, and the first
element may refer to some other buffer.  That may be the "correct" behavior
by some standard, but it doesn't match the documentation.
