And (needless to say) when there are refs to be fetched and also
pruned, the "shown_url" logic prevents us from giving two identical
headers "From <there>". Sounds sane.

OK, let's see how it goes.
Will replace what has been queued on 'pu'. The incremental change
relative to the old one looked sensible and I think this one is
