custom attributes per file

Hi git devs,

I have seen on your TODO list, that you plan to add tree attributes. We want to use git as a backend to store the wikipedia content in a distributed manner. The exporter [1] is already quite stable it seems. Today I started a frontend project [2] and have a feature request :-)

* Make attributes apply to trees, not just working tree.

What we need are versioned attributes per file and per tree. Currently we export each article into a file, but there is no way we could save custom attributes directly bound to it, which distributes the data which should be together. If the maximum value per attribute should be quite large, this way we could save reports of vote results bound to the article directly.

I think unicode data to an ascii key would be sufficient, but real types could provide great features in the future. Changes to these values should be signable by gpg signed commit messages like a normal checkin.

Maybe in the long run, there could be some sort of export filter mechanism. For cloning repositories, for example a copy of the wiki database based on a quality key of an article could be exported for a embedded device.
