We already have code for normal text which out puts all square brackets
as {[} and {]} in order to prevent this. This solution is of course
a bit tasteless. A more elegant way of doing it would be to enclose
the whole optional argument in curly brackets if they contain a ].
This would give
\begin{description}
\item [{$]$}]blah
\end{description}
I guess all it takes is to output the arg in a stringstream first, and
then check its contents.
