Comment (by chionsas.org):

 Ok, accepting two parameters is a good workaround (should have thought of
 that one myself), but I still don't understand the need for the first
 parameter (since it's always an empty string).. :?

 I understand the purpose and use of post_gallery filter (I'm using it to
 completely replace the gallery_shorttag() function with one of my own),
 but still don't get why there are TWO arguments passed, when even the
 original gallery_shorttag() function takes in only one (an array of inline
 attributes).
