Note, this can be automated with `b4`.

	# Start a new branch of the same base
	git checkout -b v3 ...
	# Apply last version from the mailing list
	b4 am $MESSAGE_ID_OF_v2
	# Do actual development of v3
	...

Also you can do more with `b4 relay`, but I haven't tried it, so I don't know
if it makes it possible or better.
