First I'm not sure if you prefer me to post to the bug or the mailing list
so please tell me if I should restrict myself to the bugs list instead..

Anyway, I think that it's an actual bug with cua-mode or something because
the deactivate-mark-hook isn't fired when the region is removed, repeated
pressing of C-g doesn't fire it either.
It's also a consistent behavior, when cua-mode is active the
deactivate-mark hook is not fired

(by using git blame) I noticed that there was a change in September last
year or something which modifies some bits about how cua-mode handles the
mark.

Please tell me if I'm wrong or if there is some additional digging I should
do to further diagnose this issue..
