--envelope-sender=foo@bar.com would imply --add-envelope.

I agree, but --envelope-sender=from looks a bit strange to me.

I think "auto" is the least worst option right now.

I also thought about having an identity (profile) for sendmail; it
would be very useful to specify the smtp server, aliases file, and
from address that multiple repositories can share and can be easily
changed (working for my company vs working for myself).

However, even in this case I would like to have a global option to add
the sender automatically from the 'from' address.
