Useful, thanks.  I pasted this in.

Yes, that would be good.  At present the linkage is so poor that things
could get lost.

I guess one thing we could do is to include the proposed manpage update
within the changelogs.  That way it's stored somewhere and gets reviewed
alongside the patches themselves.

That's late, IMO.  Sometimes reviewing manpage updates leads people to
ask "hey.  what about X" or "hey, that's wrong".  Michael Kerrisk was
