Fwiw, patchid: doesn't account for some cases where non-standard options
are used for generating patches (e.g. -W, -U<n>).  Admittedly they're
rare cases...

I've been favoring searches for postimage blob IDs (since pre-patchid
in public-inbox), possibly combined with Subject: phrase matches.

Fwiw, public-inbox can show git commits and prefill search forms:
https://public-inbox.org/git/d1e76d5ddcacdfc76bc247e7594e3fbaaa5ea9cc/s/

the top search form has `patchid:' pre-filled, and the form below the
patch has `dfblob:' pre-filled.  Subject (`s:') isn't pre-filled, yet
(haven't decided how to signify that's optional in the UI).
