I can definitely see why you'd want this, but Meld doesn't have any
real support for this.

I feel like the best way to do what you want is probably to perform a
fake merge that includes the commit you want to exclude, and the diff
the intermediate result... though honestly I'm mostly guessing. If you
do figure it out, please let us know! This does sound like it could be
generally useful.
