From: Andrej Shadura <andrew.shadura@collabora.co.uk>
It is possible for a user to disable attribute-based filtering when
committing by doing one of the following:
* Create .git/info/attributes unapplying all possible transforming
attributes.
* Use git hash-object and git update-index to stage files manually.
Doing the former requires keeping an up-to-date list of all attributes
which can transform files when committing or checking out.
Doing the latter is difficult, error-prone and slow when done from
scripts.
Instead, similarly to git hash-object, --no-filter can be added to
git add to enable temporarily disabling filtering in an easy to use
way:
* Add new flag ADD_CACHE_RAW to add_to_index()
* Add new flag HASH_RAW to index_fd()
