Yes.  I wonder why you take the time to generate the output and email
it but then stop there instead of just sending patches?

grep -A5 TRIVIAL MAINTAINERS

Perhaps Jiri can pick up some of the patches that remove stale config
symbols, correct typos etc.

Yes, these corrections take care of cruft.  But I think installing
output of scripts on wiki pages and asking for other people to fix
them up is more than these things deserve.  It's a bit like writing a
list containing

	- wash up mug
	- grind beans
	- boil water
	- put grinded beans in mug
	- put filter in mug
	- put hot water in mug

instead of just making coffee already.
