Bug#761200: debbugs: add bug number to first mail in a bug (probably via proper header)

Package: debbugs
Version: 2.4.2~exp1
Severity: wishlist

Dear Maintainer,

   * What led up to the situation?

     Use of mutt and mbox mailbox served at Debian BTS
     (e.g., https://bugs.debian.org/cgi-bin/bugreport.cgi?mbox=yes;bug=760799)

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

     I often download an mbox via the links above and give it to mutt.
     Then I have a nice mail thread that I can explore and respond.

   * What was the outcome of this action?

     The first mail in the mbox is a submission which is sent to
     "Debian Bug Tracking System <[email protected]>". When I respond
     with "r" I respond to the author which makes a lot of sense. However,
     when respond with "g" (group respond) I respond to both the author
(correct)
     and "submit@" address (wrong).

   * What outcome did you expect instead?

     I would like to see <bug-number>@bugs.debian.org instead of
     submit@... when I group respond. If this is not possible (changing To: is
     not an option, I guess, and I couldn't find an equivalent of Reply-To: for
     destinaton), I would like a custom header added to the submission mail so
that I can
     detect the bug number with my personal script.

Cheers,
Tomasz
