Using setf is better than using the previous advice, because it was
ignoring the arguments passed to evil-insert-state and the arguments
control whether the state message displays in the minibuffer. In this
version we just switch out the function definition for
evil-insert-state, and all arguments are handled perfectly.
spacemacs-core: Don't defer hybrid-mode
hybrid-mode is now extremely lightweight, and deferring it causes
problems if someone wants to bind keys in hybrid-mode but doesn't have
it selected as their editing style on startup. The reason is the
hybrid-mode keymap will not be available and an error will be thrown.
This requires using eval-after-load in this case, and this seems overly
complicated just to avoid loading this file.
Helm seems to treat "!" specially in pattern matching, so having a ! in
the pattern string when traversing directories is problematic. This
change fixes#2737, because as far as I can tell "+" has no special
meaning in a helm pattern.
Of course, we can choose a different character, but I'm fond of "+" as
representing "more layers here".
