I think we might want to have a flag that says "don't care about filesystem modes". That should be pretty easy, I think we'd get most of them by just adding some logic to "ce_match_stat()".

Then add a "git chmod" to set the mode in the index (which should end up being just a wrapper around the regular "git-update-index" using the "--cacheinfo" flag, I think).

Those parts should be trivial.

The more interesting issue is how to set the _flag_ that we should do this. We may have to add a config file, and it should be per-repository (ie something like ".git/config" or ".git/info/config"). Or do we just do yet another environment variable?
