 wp_make_link_relative() simply returns the URL passed to it when the URL
 has no path, just a domain name.  Instead, it should return a zero length
 string.

 A URL with a path of '/' correctly returns '/'.

 Incorrect:  var_dump( wp_make_link_relative( 'http://www.wordpress.org' )
 ) displays "string(24) "http://www.wordpress.org"

 Correct:  var_dump( wp_make_link_relative( 'http://www.wordpress.org/' ) )
 displays string(1) "/"

 Workaround:  for my purposes, parse_url( $home_url, PHP_URL_PATH ) does
 all that I need, but wp_make_link_relative() would still be useful when a
 Query or Fragment is present in the URL.
