If you throw in more than two endpoints, the result is a combined diff
with respect to the first commit. You can have some fun with that, eg
"git diff -c @ @~4 @^^2~4".

Well, I think the most confusing part is to have this undocumented
around. The range notation are basically just the same symbols for
git-diff, but the meaning seems to be quite different. If this is going
to stay - shouldn't there be at least some documentation for people
trying such stuff out? And that we can point to? Or is there a reason to
keep this undocumented?
