I think a much more general approach would be to turn your script
into "get-msg-id" script and use it like so:

  $ git format-patch --in-reply-to $(get-msg-id <mboxfile>) a7fe7de8

Then you can reuse that script in a context outside format-patch,
whereever you need the message-id in a single message in the
mailbox.
