 Construct a relative url to the first parameter from the page named by the
 second. The first parameter can be either a page name, or some other
 destination file, as registered by `will_render`.
 
-If the second parameter is `undef`, the URL will be valid from any page on the
-wiki, or from the CGI; if possible it'll be a path starting with `/`, but an
-absolute URL will be used if the wiki and the CGI are on different servers.
+Provide a second parameter whenever possible, since this leads to better
+behaviour for the [[plugins/po]] plugin and `file:///` URLs.

+If the third parameter is passed and is true, the url will be a fully
+absolute url. This is useful when generating an url to publish elsewhere.
