How to add/change ex-mode mapping in viper/vimpulse?

Question

really not a fan of :e and :b opening in another window, and would like to remap the functions they are calling.

AFAICT vim does not allow 'redefining' standard ex commands (:e and :b, e.g.) `:e` on my system uses the current window (you'd have to `:tabedit`, `:split`, `:vert split`) to get a different window. — sehe, Jul 03 '11 at 23:03

Viper ex commands are defined in ex-token-alist.

To add new commands (of course other approaches like consing and add-to-list are possible):

(push '("name" (do-this)) ex-token-alist)

Prior entries have higher priority than later, so if you want to override, just add them.
