Subject: [PATCH] Ticket #42 - Nachkommastellen in Menge bei
 Erzeugniskomponenten
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Danke an Joachim Zach für einen Patch, ich habe bei der Gelegenheit auch
noch ein paar Codestellen kommentiert. Das Verhalten von item_selected
bzgl. parse/format_amount unterscheidet sich mittlerweile je nachdem, ob
es in Belegen oder in Erzeugnissen verwendet wird.
