Sorry, yes. But that's the only thing they can be overridden by. That
is surely not the right thing. Consider the variable c-cleanup-list
which Jan though he was setting. Here is a list of the ways of setting
it (taken from the CC Mode manual, page "Config Basics"), disregarding
for now .dir-locals.el:
Style
Top-level command or "customization interface"
Hook
File Style
[Explicit setting in file local variables]
, in increasing order of precedence. This order seems sensible, IMO.
In particular, the File Style and local variables settings are rarely
used precision instruments, for configuring unusual files unusually.
Now add .dir-locals into the mix:
Style
Top-level command or "customization interface"
Hook
.dir-locals.el <=====================
File Style
[Explicit setting in file local variables]
Why on earch does .dir-locals.el take precedence over values set in a
top-level `setq' or `c-mode-hook'? This is surely the Wrong Thing to
do. Jan hat set his own desired value of c-cleanup-list (as a top-level
command), only to have it obliterated by this line:
(c-mode . ((c-file-style . "GNU")))
in .dir-locals.el.

Yes, we both agree on what is happening. My point is that the contents
of .dir-locals.el should not override explicit values given by the user
in his .emacs.
