The intention was that, if the Xref file contained
... comp.foo:47 repost:15
and your .newsrc file stated you had already read comp.foo up to #40, then
it would not show it to you (because 15 < 40). But if you wandered into
comp.foo for the first time (so your .newsrc would say you had not seen
anything later than #0) then you would see it.
Of course, existing newsreaders could not provide this funtionality, but
future smart ones would (and would doubtless allow you to configure it on
or off, either at the 'repost' level or at the 'revise' level).

Hmmm! I think you would have to include the Replaces head in the overview,
and I believe most newsreaders use the .newsrc file, or something broadly
equivalent.
