Expand description

For a rewritten commit, find the newest version of the commit.

For example, if we amend commit abc into commit def1, and then amend def1 into def2, then we can traverse the event log to find out that def2 is the newest version of abc.

If a commit was rewritten into itself through some chain of events, then returns None, rather than the same commit OID.
