I've applied the patch as is.  Thanks.  I'll try those new features
later.  Maybe the custom type for the new w3m-lnum-actions-* options
needs to be improved.  How about this way?

  :type '(cons (string :format "%v")
	       (repeat (group (character :format "Key: %v ")
			      (function :format "%t:\n%v"))))
