New foot-shooting-prevention helper function. (edit_msg_internal,

	* mail-callbacks.c (are_you_sure): New foot-shooting-prevention
	helper function.
	(edit_msg_internal, view_msg): If the user has more than 10
	messages selected, ask before opening them all in separate
	windows, to protect against misclicks/typos after "select all"
	(which we've had at least two reports of now).
