how many of those are default anyway? :)

I already mentioned this in a separate private conversation but for the
archives:

I'm not merging this right now because it will interfere with other patches
that are in the queue right now. we need a release for 1.10 anyway, as soon
as that is out, I'll re-run indent with the sets above before merging new
patches. that way, we should get the least amount of conflicts.

but ACK to the principle, this has been going on my nerves for a while now.

Cheers,
