Yeah, it would certainly be nice to have all the format-specifiers
that one unified parser acts on, but isn't this just a matter of
refactoring?  Shouldn't we be starting with cheap callbacks, get
things working, and guard against regressions in the refactoring phase
first?  How else do you propose to start out?

Ofcourse.  I didn't notice %(objectsize); %(objectsize[:disk]) is a
fine suggestion.

Oh, I'm proposing that Peff implements just %H and
%(objectsize[:disk]) for _now_, because that's what he wants.  It
should be a tiny 20-line parser that's easy to swap out.

Agreed.  The approach paints us into a design-corner, and must
therefore be avoided.
