Re: [PATCH 5/7] sha1-file: pass git_hash_algo to write_object_file_prepare()

> Allow write_object_file_prepare() to receive arbitrary 'struct
> git_hash_algo's instead of always using the_hash_algo. The added
> parameter will be used in the next commit to make hash_object_file() be
> able to work with arbitrary git_hash_algo's, as well.
