Maybe a bit overkill, but I needed more flexibility around adding
arbitrary whitespace.
New modifiers:
%s A space
%{ Start a substring
%}s End and format a subtring
%aaa[mod] Repeat this mod aaa times
With this, it's easy to add arbitrary spaces:
"%8s" -> " "
Or equivalently:
"%8{ %}s" -> " "
Which allows arbitrary repitition of any substring:
"%4{hi!%}s" -> "hi!hi!hi!hi!"
This substring modifier includes its own format string, which allows for
some really nice padding normally impossible in printf:
"%{%(a)d/%(b)d%}8s" % {a:1,b:2} -> " 1/2"
"%{%(a)d/%(b)d%}8s" % {a:12,b:34} -> " 12/34"
