What an useful way to describe kernel version.

Could we get reasonable subject line? 4.15-rc7: prefix would be nice
if it is on mainline, net-next: subject if it happens only on next

We don't want dumb bots to send automated emails to 1000s of
people. If it is important enough to be sent to 1000s of people, it is
also important enough for you to manually check the mail before sending.

...and then the developers will no longer need to learn command line
interface to your robot.

If there's some other bot reading this: you may not want to
