As of revision 116, the problems with wrapping mixed arrays whose ⍕ is of
⎕PW width (or ⎕PW-1 before r113) still persist.
But there is another issue with wrapping which I think may be related.
When displaying nested vector whose elements are vectors, only the first
element is treated as expected. All subsequent elements only start a new
line when they were to wrap and then continue without wrapping past ⎕PW.
