 * -p should probably go "_two_ more hops" on <FRAMESET> pages.
 
-* Only normal link-following recursion should respect -np.  Page-requisite
-  recursion should not.  When -np -p is specified, Wget should still retrieve
-  requisite images and such on the server, even if they aren't in that directory
-  or a subdirectory of it.  Likewise, -H -np -p should retrieve requisite files
-  from other hosts. 
-
 * Add a --range parameter allowing you to explicitly specify a range of bytes to
   get from a file over HTTP (FTP only supports ranges ending at the end of the
   file, though forcibly disconnecting from the server at the desired endpoint

+	* recur.c (retrieve_tree): Skip the non-inline entries when
+	enqueuing the children of a leaf HTML node in -p mode.
+	(descend_url_p): Ignore opt.no_parent when in -p mode and UPOS is
+	"inline".
+
+	* html-url.c (get_urls_html): Don't accept dash_p_leaf_HTML.

+	acceptance/rejection rules.
