Neat. There was discussion on a similar issue recently in:

  https://public-inbox.org/git/305577c2-709a-b632-4056-6582771176ac@redhat.com/

where a possible solution was to get senders to use in-body From
headers even when sending their own patches.

This might provide an alternate solution (or vice versa). I kind of like
this one better in that it doesn't require the sender to do anything
differently (but it may be less robust, as it assumes the receiver
reliably de-mangling).
