By default, Evil treats an insertion as a single undo step. You can
disable this with `evil-want-fine-undo':

    (setq evil-want-fine-undo t)

That leaves undo boundaries up to Emacs, resulting in a more
"fine-grained" undo.

To change the Insert state binding of "C-w", modify
`evil-insert-state-map':

    (define-key evil-insert-state-map "\C-w" 'undefined)

That makes "C-w" do nothing in Insert state. Alternatively:

    (define-key evil-insert-state-map "\C-w" 'evil-window-map)

That gives you window navigation in Insert state as well.
