	* reverse.c (delete_one_bookmark): Argument is now bookmark
	id rather than pointer to bookmark struct.
	(delete_bookmark_command): Use get_number_or_range.
	(goto_bookmark_command): Parse with get_number instead of strtoul.
	(bookmark_1): New function.  Print info for one bookmark.
	(bookmarks_info): Use get_number_or_range and bookmark_1.
