I'm not completely sure, but I guess what you want is:

Show the difference between the merge-base of master and topic, and the
worktree.

You can accomplish this with:

git diff $(git merge-base master topic)

I guess a shorter notation for that could come in handy. OTOH, I usually
diff against HEAD in a situation like that.

Great solution. I feel silly now, the answer ended up being rather
obvious. I can create an alias for that. But I can't diff against HEAD
because then I am not seeing a diff of changes already committed.
Thanks for your help.
