How to keep Reviewed-by lines in git commits with gerrit.

[Carlos O'Donell]

Florian,

If we ever switch to supporting Gerrit, then we will automatically
gain the Reviewed-by: lines depending on the configuration of Gerrit.
Reviewers would understand this as part of doing their reviews and
granting the review +1/+2.

In the meantime I can do two things as a reviewer to help you keep
the Reviewed-by lines.

1. If I am about to grant +2 review I edit the commit and generate
   a new patchset version, and add my Reviewed-by line.
2. I submit my review of +2.

Then when you push, you just need to make sure your new commit message
matches and it should close the review.

Carlos.
