#22354: Gravatar Shouldn't Use images/blank.gif

 There is a very subtle flow-of-control error in pluggable.php:

 {{{
         elseif ( 'blank' == $default )
                 $default = includes_url('images/blank.gif');
 }}}

 This makes sense when $email has no value, because it will cause the local
 blank.gif file to be displayed.  However...

 When $email is not empty, this function is causing the gravatar.com server
 to make a proxy request to the blank.gif file and display the local file
 through a remote request.  This is not the intended behavior.  When the
 $email value is present, the Gravatar request should simply contain
 "&d=blank" to get a blank image.
