You could keep it at the top, but then I'd be inclined to split up
the existing code:

        int            trgindex;

        CHECK_FOR_INTERRUPTS();

        /* Get index of next trigram */
        trgindex = trg2indexes[i];

        /* Update last position of this trigram */
        ...

What's annoying me about the one-liner fix is that it makes it
look like CFI is part of the "Get index" action.
