Assert

[Andre Poenitz]

I think there are a few places in InsetText that are never reached.
Should I put in a lyxerr<< or an Assert or ...?


I.e. 

LyXCursor const & InsetText::cursor(BufferView * bv) const
{
        if (the_locking_inset) {
                lyxerr << "InsetText::cursor(). Should not happen!\n";
                return the_locking_inset->cursor(bv);
        }
        return getLyXText(bv)->cursor;
}
