bug#21247: 25.0.50; Wrong type argument: commandp, hi-lock-find-patterns

[Nicolas Richard]

from -Q, I hit M-s h f and I get :

command-execute: Wrong type argument: commandp, hi-lock-find-patterns

a void-function error happens with C-h k M-s h f.

I have a build from the emacs-24 branch where the problem is present
also, but C-h k M-s h f says:
M-s h f runs the command hi-lock-find-patterns, which is an alias for 
`hi-lock-find-patterns',
which is not defined.  Please make a bug report.

Should we add an autoload ?
