The changes related to issue #3068 removed most of the emacs bindings from vi mode. However, since fish 2.4.0 was released several people have pointed out that the directions for reinstating the legacy hybrid key bindings don't work. This change fixes that and makes it easier to use the legacy hybrid bindings. Fixes #3556
