Subject: [PATCH] KiviLatex-Template-Plugin: leere Listen entfernen
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Das sind Einträge, die im HTML so aussehen: <ul> </ul> LaTeX schmeißt
beim Äquivalent (\begin{itemize} \end{itemize}) Fehler. Kann z.B. via
Copy & Paste aus LibreOffice passieren.
