> we don't need another bit for now, 4-bit signed is sufficient for this.

there's only 3 in svshape4.

svshape4, 2nd mode:
--------

 945 | 0:5|6:8|9:10|
 946 | -- |---|----|
 947 | PO |SVo|si  | 

it's pretty normal to get confused between the instruction(s)
and the SVSHAPEs tht the instructions update/modify.
