I've noticed quite a few messages with identical Message-IDs,
especially with /all/ (*)
a) There are occasionally resent revisions of patches with the
same Message-ID
b) More often, a cross-posted message has different trailers
depending on which list it was posted to. (And the
PublicInbox::Filter::* API doesn't apply at indexing,
only at git injection time)
I'm thinking of two new features:
1) the WWW and lei UIs could have a "diff mode"
that clearly shows differences between rendered texts
This could be expensive with malicious inputs, but the
existing "limiter" infrastructure used for serving packs
should help, here.
2) support PublicInbox::Filter at index-time
(requires reindexing to take effect, will cause new IMAP
UIDs+NNTP article numbers to show up, possibly en-mass)
