branch is never empty since you are providing a default.

This also seems to fail silently (actually displaying a wrong info) if
one  does dim range-diff HEAD^

It would sound more useful if falling back to git-tbdiff in case
range-diff is not available. What I kind of dislike on wrappers is the
inability to provide more arguments. One that would be useful here
would be a --no-patch if one only wants to see status change, not the
change itself.

I'm still getting used to the tool so I'm always explicit: I always
type both  ranges to tell exactly what I want to compare.

git range-diff basecommit..origin/branchname basecommit..HEAD
