The other problem that would have to be considered is cross-branch
variation in the indent rules. We've generally been in the habit of
back-patching HEAD diffs without worrying about whether they meet
back-branch rules; certainly nobody maintains typedefs.list in the
back branches. Maybe the most expedient answer for that is to only
enforce indentation in HEAD.
I'm still not really on board with this though. I can definitely
see the day coming when it would block a security patch and somebody
would be scrambling desperately to fix their indentation under time
pressure, even though perhaps the patch had been fine when created.
