Umm, that seems rather AI-complete.  You should always compile the list
by hand.

For example, the list in this case started

      25  SZEDER Gábor
       4  Michael J Gruber
       3  Teemu Matilainen
       3  Thomas Rast

Would you Cc Michael, Teemu and me?  Probably not.  What if it started

       5  SZEDER Gábor
       4  Michael J Gruber
       3  Teemu Matilainen
       3  Thomas Rast

Also, something I didn't mention so far was that you may be patching
squarely into the code of one contributor, even if he only had a single
patch in that area.  To catch this, you should blame the code you are
fixing (you already checked the message of the commit to verify whether
the bug/feature was intentional, right?).  On top of that, the patch may
have involved a large number of people not listed in the Author field.
As a random example,

  $ git shortlog -sn --no-merges v1.7.0..origin/next -- grep.[ch] builtin/grep.[ch]
      15  René Scharfe
       9  Junio C Hamano
       8  Nguyễn Thái Ngọc Duy
       5  Michał Kiedrowicz
       4  Johannes Schindelin
       3  Jeff King
       3  Thomas Rast

but if you were to submit a patch that disputes the case made by
53b8d931, you should probably cc René, Peff and me (see the Helped-by
lines).

Ok, this got rather long-winded.  But I think the bottom line is, trying
to put this in sendemail.cccmd is trying to script common sense.
