How to list commit divergence between local branch and remote branch

[ca1f]

Hi,

how would you list all commits that are different between a local branch and a remote reference? I found this issue here that seems to talk about how to solve this problem: src-d/go-git#757 (comment) but when I toyed with the given snippet, it only shows commits if the local reference is ahead. If the remote reference is ahead of the local branch, it doesn't list the commits that are present in the remote branch but not in the local branch.

What I basically would like to do is to implement what git status --short outputs:

## main...origin/main [ahead 1]

or

## main...origin/main [behind 1]

but I would like to also see which commits are different.

I feel like the solution to my problem is really obvious but I can't see the forest for the trees.
