Darcs does not have immutable history. It uses hashes instead of integer
versions (because of being distributed), but it computes the hash like
this:

http://progetti.arstecnica.it/tailor/browser/vcpx/repository/darcs/source.py#L495

So basically the commit hash does not use the hash of the commit
contents, only the commit date/author/message/etc.
