I think you lost the context of my remark.  It was referring to widths that
are specified pragmatically.  Here's the context:

My point is that once you're in programmatic land anyway, the translators
are out of the loop and you might as well just use a local manipulator.

Of course, width specification should still be supported in the format
string for non-programmatic cases.  (Plus a translator could always override
a local manipulator's width specification, if so desired.)
