The point is that the Link: tag connects the commit to the email by
which it was submitted.

If the committer fixes something up when committing, then this still stays
the same connection.

So you have SHA1 + Message-ID. If the SHA1 changes and Message-ID stays
then same, then either the patch was amended or rebased. But you can figure
that out with diff.

Thanks,
