Git doesn't keep a history of sha1-ed patches -- it's a history of
commits, each pointing to a tree and a parent commit(s). If we both
have the same <sha1>, then `git log <sha1>' in both of our repository
is guaranteed to be exactly the same graph, same author, dates, and
log messages -- they're all part of the resulting hash.
