[ This is getting very far from Emacs, but I find it interesting, so here
  I am.  Did I say it was my last message in this thread?  ]

My view on this is that we need to distinguish the tree from the ways to
get to it.  So, the revision would get a hash which only depends on the
files in it and not on the commit message, nor the author, nor the
parent revisions.  Then the arcs between revisions (i.e. the patches)
would have their own hash which would take into account the author, the
commit message, the date, and of course the hashes of the "from" and
"to" revisions.
