It didn't occur to me that the two could be treated differently,
especially since the Note in 22.214.171.124.2, p2 goes on to say:
...For the value af equal to (str.flags() & str.adjustfield),
if (af ==str.internal) is true, the fill characters are placed
where none or space appears in the formatting pattern; ...
Or am I still missing something?
