Here's a little wishlist for send-email

- Use From: field extracted from patch:
  If there's no configuration for user.email and From: field is 
  different than default auto generated From: address, 
  git send-email should use the one in the patch as default.

I cannot judge how sensible this change is; please justify the motivation
by adding "it currently does _this_, which is not good for _such and such
reasons_; instead" between the third and the fourth line.

- Use To: field extracted from patch
  I've setup format-patch to add a default To: field with
  format.headers="To: xxx@yyy". But git send-email did not use it and 
  ask for a To: value.
  If there's no --to or sendmail.to, send-email should use To: value 
  extracted from patch and ask for user confirmation.

With the recent addition of format.to that is cooking somewhere, I think
this one is probably sensible.
