Serving message-id lookups from /all/

[Konstantin Ryabitsev]

Hello:

When using message-id lookups, the results are returned from individual lists,
e.g.:
    https://lore.kernel.org/20210901141637.fmvgs4hnk6m4ym7x@meerkat.local

This will redirect to:
    https://lore.kernel.org/tools/20210901141637.fmvgs4hnk6m4ym7x@meerkat.local/

Any way to have the message-id lookups be served from /all/, to make sure that
we see threads reconstituted from across all lists?
