[PATCH 0/5] clone|fetch: flesh out partial mirror support

[Eric Wong <e@80x24.org>]

The --epoch=RANGE feature discussed last week[1] is implemented.
There's also a bunch of fixes and improvements for handling
partial fetches from work started last week.

There's also a significant amount of work done to ensure the
client-side code works on servers running old, pre-manifest
versions of public-inbox.

I'm not sure if there's pre-manifest.js.gz versions of
public-inbox out there, but it's only ~2 years old and I can
understand if some admins have been preoccupied with the
pandemic and unable to upgrade :/
