The Org fragment \[ r = a + b - c \]
gets interpreted as something strange with a list inbetween. Thus it gets
exported as:
$\backslash$[
r = a
\begin{itemize}
\item b
\item c
\end{itemize}
$\backslash$]
How is one supposed to write (longer) equations out on multiple lines (leaving
the operators behind on the previous line obviously works, but is ugly)?
