Thanks, it now works, but then... You forgot to add the Cc: entries for
all the people in your actual e-mail Cc: list, and also the
Reviewed-by: from Andy, I had to do it all manually, so when I applied
your attachments with 'git am' I needed to go on and manually collect
all the Cc, Reviewed-by and Acked-by tags.

This complicates things, slows me down, doesn't scale. While I do all
this manual stuff normally, I don't think this can continue, and its not
something specific to you, submitters have to pay attention to these
details. Or tools.

Things like b4 help with this and probably have to take into account
attachments as well, that is why I'm adding Konstantin to the Cc: list
of this message.

Konstantin, is this case covered? I.e. patches that get botched and then
require attachments to be sent to then gets processed?

Thanks, applied.
