It will pick up all trailers sent to that patch, matching it by patch-id. You
can see where every trailer came from if you run "b4 -d". E.g.:

Looks like a lot of these came in response to stable review requests, sent to
the cover letter.

This is generally the desired behaviour for b4 -- if someone sent a trailer to
a patch, we want to reflect it even if it was received for a previous revision
or when the patch was posted as part of a different series.

I'm happy to make more nuanced exceptions for special-case situations like
stable reviews.
