It is brave of you to make such large changes the first time.  ;-)

(Your change seems fine to me.)

  I choose for the "carry", as for rsblsh1 and rsblsh2...
  But I tested it only inside fib2_ui, where the borrow (carry=-1) can not
  be triggered.
  
I suppose an addition to tests/devel/try.c is called for, at some point.
