That will probably work fine when operating locally on (short) temporary
branches.

It would probably become computationally prohibitive to use it between
long lived permanent branches.  In that case it would need to be
augmented by the sha1 of the originating commit.  Which gives you two
hashes as reference, and in that case you might as well use the two
commit hashes of which the difference yields the patch.
