evil-set-initial-state not working for several modes

[Leo Alekseyev]

I have the following lines in my .emacs:

(evil-set-initial-state 'magit-status-mode 'emacs)
(evil-set-initial-state 'magit-log-edit-mode 'emacs)
(evil-set-initial-state 'shell-mode 'emacs)

as well as other initial-state directives, but these in particular
don't seem to work.  All these modes start in the normal state.  I
suspect this is a bug; can somebody confirm it and/or give any
bug-hunting advice?
