    vim: fix ctrl-[ to escape from insert mode
    
    ctrl-[ should always be a synonym for Escape but it's only currently a
    synonym for Escape in one of the two places Escape is specified.
    
    This commit adds a duplicate entry for the other place, too, and fixes
    escaping from insert mode using ctrl-[.
