[TYPO3-shop] Linebreak in ordrelines

[Sus]

Hi

I the ordre e-mail I use plain text.
I want the productlines in just one line with no empty lines inbetween.

My template is:

<!-- ###ITEM_CATEGORY_AND_ITEMS### -->
<!-- ###ITEM_LIST### begin -->
<!-- ###ITEM_SINGLE### begin-->###PRODUCT_ITEMNUMBER###  ###FIELD_QTY### 
stk. ###PRODUCT_TITLE###  (af ###PRICE_TAX### kr.) ###PRICE_TOTAL_TAX### 
kr.<!-- ###ITEM_SINGLE### end -->
<!-- ###ITEM_LIST### end -->
<!-- ###ITEM_CATEGORY_AND_ITEMS###  end -->

But I still get this with an empty line inbetween each:

93-700  3 stk. Tallerken Reol 100 stk.  (af 300,00 kr.) 900,00 kr.

35-002  3 stk. Serveringsbakke  (af 8,50 kr.) 25,50 kr.

35-001  3 stk. Tjernerbakke rund  (af 8,00 kr.) 24,00 kr.

How can I remove this empty line?
