Thank you! That is EXACTLY what I'm raising. What's more, the
overriding is surreptitious - it took Jan some time to find out what was
going wrong. How do you turn off this .dir-locals.el thingy?
I agree with Miles:

No. They should act as a project wide default, which a user can
occasionally vary as he sees fit. The problem is not that .dir-locals.el
exists, but that it takes precedence over a user's c-mode-hook, or a
top-level (setq c-cleanup-list) in .emacs. Jan complained that he was
left with no way to set c-cleanup-list. (M-: (setq ....) doesn't count
as "a way" here.)

Hey, that's not fair!
c-cleanup-list is partly project conventions (in that it can implement
formatting rules), partly personal preference (in that it enables
electric action in a C buffer). For example, a project may specify the
'brace-else-brace' convention (see page "Clean-ups" in the CC Mode
manual), but a hacker may not want this to be done electrically in his
Emacs.
