Mon Jul 6 05:42:02 CEST 2020
It is tedious to add review tags into the local branch and errors can
sometimes be made. Add an option to create a new branch with the review
tags obtained from patchwork.

+To automatically pull into these tags into a new branch, use the -d option:

+This will create a new 'mtrr4' branch which is the same as your current branch
