Wait. Author: should not be overwritten when it already exists (i
set it, i think certain Thunderbird devs mentioned on some IETF
list they started supporting it, or so), says 9057:

   Processing of the Author: field follows these rules:

   * If an Author: field already exists, a new one MUST NOT be created,
      and the existing one MUST NOT be modified.

Whereas you simply create a second one.
I myself find

  via suckless dev list <dev_at_suckless.org>

excessive, given that

  via <dev_at_suckless.org>

is shorter and more to the point.

I very much like that "Laslo Hunhold (dev=frign.de)" thing, but am
a bit afraid that many MUAs will simply remove the comment; granted
creating a correct quoted-string is not easy, but placing all in
one may be a thing.
