Did you test your function? It segfaults my program when I use it like
that, that is, without doing anything except of calliing cur.isRTL():

Maybe we should remove this assertion in the const access method...
But anyway, I've just committed a new method that will give you this
information: bool Cursor::isRTL().
This methods only give the RTL state of the current paragraph so it will
not work for mixed language paragraph.
Please send a patch when you are done.
