C-SPC C-<left> weirdness

[Michael Olson]

I'm noticing that whenever I do the key sequence C-SPC, hold both keys,
then hit <left> multiple (at least three) times, the minibuffer flashes
rapidly with the messages "Mark deactivated" and "Mark activated".  This
is a regression that does not happen with my build from Sep. 12.  The
expectation is to keep the mark activated while pressing <left>.
