qe.c: open_below() should call open_above() with count

[cziesler]

In open_below(), the call to open_above() should pass in the count variable instead of 1.

void open_below(uint16_t count)
{
    cursor_down(1);
//  open_above(1);
    open_above(count);
}

Yup, fixed --- thanks!

Of course, as text_insert() currently ignores the count this is strictly academic, but that's not the point...
