I'll start by saying that, well, I'm pretty sure this patch is wrong.
I was trying to look at the changes between two commits, sanely, but
failed to find a tool or example in the tree that hinted at how to do
this.
After poking around at git-whatchanged trying to figure out what it is
trying to do - I gave up and wrote something that *seems* to work
correctly for the simple test cases I pulled together. I just don't
trust it.
My thinking here is that, when doing a release of a package such as git
or Linux, the releaser could do something like:
git changelog $LAST_RELEASED_COMMIT HEAD | git-shortlog |\
mail -s "Linux 2.7.0 finally open" linux-kernel
Where LAST_RELEASED is recorded somewhere or pulled from an internal
changelog with something like:
grep "Released commit-id:" changelog | awk -F: '{print $2}'" |\
head -1
