From: "Eric W. Biederman" <ebiederm@xmission.com>
To create the proper signatures for commit objects both versions of the commit object need to be generated and signed. After that it is a waste to throw away the work of generating the compatibility hash so update write_object_file_flags to take a compatibility hash input parameter that it can use to skip the work of generating the compatability hash.
Update the places that don't generate the compatability hash to pass NULL so it is easy to tell write_object_file_flags should not attempt to use their compatability hash.
