Hi-lock is asking to apply patterns in the help buffer because it's
matching its own example patterns, not patterns any user meant to
actually apply.

  When hi-lock is started and if the mode is not excluded or patterns
  rejected, the beginning of the buffer is searched for lines of the
  form:
    Hi-lock: (FOO ...)

It's not helpful to prompt the user in this case, especially not for
help invocations unrelated to hi-lock.
