just in case are you aware of this discussion regarding goto labels
http://lkml.iu.edu/hypermail/linux/kernel/0706.0/0809.html ?

Practically there is no big need (neither it is a clean-up IMHO)
to change column 1 indentation of goto labels, however I do agree that
^[a-z0-9_]\+:$ style of goto labels is 10 times more commonly used,
and that means it's a good time to update my ~/.emacs config.

Someone may want to fix the style of another 5000+ goto labels one day,
though it is better to have an officially agreed policy beforehand.

Anyway I do not strictly object against the change, see one my comment
below and feel free to add my

Since you are here, can you sort headers out, please?

And I'm pretty sure some more inclusions can be safely removed
from the list.
