Ctrl-C when in command-line mode doesn't work anymore

Seems like snapshot 154 broke this functionality. Pressing Ctrl-C in command-line mode doesn't break out of it anymore, but a follow-on key press would.

Seems like e40b9d4 (v8.1.0834) broke this. It could either be a bug in Vim or a merge error on MacVim's side.

Also, remapping cnoremap <C-c> <Esc> does not work. :/

I'm facing the same issue. Pressing ctrl-c in any mode causes a spike in CPU usage and a noticeable delay. The issue only seems to occur in when using the MacVim gui. (so it doesn't seem to be an issue on the vim side).

I'm still looking into this, but the CPU usage bit is interesting info. Just for context MacVim relies on the GUI codebase in Vim itself and basically works as a special type of gVim. That's why when Vim's GUI code goes through refactor like this, sometimes bugs creep in despite a clean merge since we have to re-do some of the changes downstream to match the upstream changes.
