+ * format incremented to 230.
+ * Support for a second optional argument in insetcommand.
+ currently, citation uses this to support natbibs second
+ optional argument \cite[before][after]{key}.
+ I think there's nothing to convert upwards. Downwards, the
+ commands need to be converted to ERT I suppose.
