[downloads] shortcode – loop for empty

Hi,

I gone wild and created own tree for downloads (see Dokumenty).

It looks like:

'[downloads
	category="'. $category['slug'] .'"
	category_include_children="false"
	template="button"
	loop_start="<div class=\'download-category\'><'. $tag .'><a href=\''. get_permalink() . $category['slug'] .'/\'>'. $category['name'] .'</a></'. $tag .'>"
	loop_end="'. htmlspecialchars($children) .'</div>"
	before=""
	after=""
]'

Where:

• $category is current category (from friendly URL).
• $tag is hierarchical number for header.
• $children is calling to itself of function – $children = ( count( $category['children'] ) ? print_categories( $category['children'], $i_tag + 1 ) : '' );.

I have one of main category, which have nothing in itself – Pozostałe pliki – however childrens have, for example Pozostałe 2011/2012

As you can see they appears in dropdown and files’ main page as I set 'hide_empty' => false, for queries.
Can I set something similar to [downloads] shortcode, as I don’t see anything related in documentation (category_include_children don’t do the job as then files are cloned under parent and children)?
As summary – I need to loop_start and loop_end were executed depending not on if certain category is empty of files.

(Maybe I could check for source code for myself, but I will fall asleep in a moment and maybe above code will be useful for future readers.)

Thanks in advance,
Greetings
