Right.

As you mentioned above.  if you point it at the statement, rather than the
compound_expr containing it, it can't go backwards.

I think bsi_prev is actually broken, in that it doesn't do the opposite of
bsi_next/bsi_stmt in this regard (IE it should look in the first operand
of a compound_expr, like bsi_stmt would, when trying to find the prev)
