blob: optionally read attributes from repository When `GIT_BLOB_FILTER_ATTTRIBUTES_FROM_HEAD` is passed to `git_blob_filter`, read attributes from `gitattributes` files that are checked in to the repository at the HEAD revision. This passes the flag `GIT_FILTER_ATTRIBUTES_FROM_HEAD` to the filter functions.
