I have always hate the idea of automated patches from random people
because I don't trust them to not be malicious so I have to review them
manually.  There is a story that back in the day the US government paid
someone to send tons of checkpatch style patches to BSD.  The guy
thought he was "cleaning up the code" but actually he was part of a
larger scheme to flood the maintainers with patches so another person
could slip in some malicious code.

It's better if someone just ran this on all new staging code before
adding it to the tree.
