C-SPC C-<left> weirdness

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>.

Why would you continue to hold down C-SPC while hitting <left>?

If you hold down C-SPC, it's eventually going to start auto-repeating
(which would yield flashing messages like you see), though I imagine
<left> _should_ cause X to "cancel" the auto-repeat state of C-SPC
(it does for me); if not, I guess that could be an X bug.

[Repeating C-SPC seems to now toggle active mark state, which I guess is
new behavior (or at least I don't recall it seeing it before), but seems
reasonable enough.]

[See end of bug #40, toggling behaviour was there around april 2008, at
least for the transient-mark-mode on case]

It requires less coordination of finger movement.  Otherwise I'd have to
keep Control pressed and take the thumb off of SPC.

I guess the more precise description of the problem is that C-SPC
autorepeats when held down, and it shouldn't.  It didn't start doing
this until this week.  I'm going to try out the current HEAD code on
another machine today to see if it's just due to an upgrade of my home
machine.

Hmm, does this really have anything to do with Emacs though --
isn't it X that determines when/how to autorepeat?

On my other machine, I am noticing that C-SPC does autorepeat, but not
when I hit C-SPC <left> and hold C-SPC.  This machine has an older
version of X.  So I guess it's an X bug.  I'm not sure how to go about
reporting this to the X.org maintainers.
