No, not "git reset --hard" either, I think. Git very much tries to avoid 
rewriting files, and if you've told it that file contents are stable, it 
will believe you.

In fact, I think people used CE_VALID explicitly for the missing parts of 
"partial checkouts", so if we'd suddenly start writing files despite them 
being marked as ok in the tree, I think we'd have broken that part.

(Although again - I'm not sure who would use CE_VALID and friends).

If you want to force everything to be rewritten, you should just remove 
the index (or remove the specific entries in it if you want to do it just 
to a particular file) and then do a "git checkout" to re-read and 
re-populate the tree.

But I'm not really seeing why you want to do this. If you told git that it 
shouldn't care about the working tree, why do you now want it do care?
