The documentation says:

> When a pane is resized from outside (eg, it is packed to expand and fill, and the containing toplevel is resized), space is added to the final (rightmost or bottommost) pane in the window.

map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]
