Kurtis Rader e8a31a13a1 make it easy to get the legacy hybrid key bindings
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
