[Nouveau] reply-to header

[Xavier]

Afaik the absence of that header is the reason that the reply button
in mail clients or in gmail answers to the sender rather than to the
mailing list.
Does anyone know why that header is not included ?
I consider it a must have for any mailing list, without reply-to it's
quite impractical.
Or is everyone used to use reply-all or something, which includes the
ML in CC, and no one does the same mistake than me ?
Maybe the problem is just me, as I only used mailing lists that filled
reply-to correctly before.
