Nice work!! This will be really helpful in situation like now where we
have to backport almost all our fixes from mainline to 3.7 & 3.8 branches.

I'd also request you to send a report on the patches missing in 3.8
branch and send a reminder to all the developers asking for the backports.

Also is there a way to limit the comparison? For an example I may be
interested in seeing the delta between mainline and last 3.7 release
i.e. 3.7.11 and do not want to compare the whole 3.7 branch?
