bug#47198: 27.1; Why bind some commands by default if they're not defined?

[Drew Adams]

emacs -Q
C-h b

There is this entry, with no link on the command name:

 M-s h f                hi-lock-find-patterns

This is apparently because file `bindings.el' adds the key binding:

  (define-key search-map "hf"   'hi-lock-find-patterns)

Is it a good idea that we do this even though the command is not yet
defined?

Seems like such a binding should be in hi-lock.el, and be created only
after the command is created, no?

(This bug is a bit similar to #47197, I guess.  But `vc-ignore' doesn't
seem to be bound anywhere.)
