git-diff-tree was about.  The only consumer of that information
so far is this git-patch-id command, which was inadequately

IOW, you can use this thing to look for likely duplicate commits.
When dealing with git-diff-tree output, it takes advantage of
the fact that the patch is prefixed with the object name of the
commit, and outputs two 40-byte hexadecimal string. The first
string is the patch ID, and the second string is the commit ID.
This can be used to make a mapping from patch ID to commit ID.
