Someone `git push --force` and I get merge conflict. 

Comparing local and remote branches I can see that (1) last two commits are replaced by (2) only one. And new `242ab72` commit was added.

Now I want to analyze how commit `5892f6b` differs from `6a53778` commit.

**Is there something similar to next command?**

```
diff -ruBN $(git show 6a53778) $(git show 5892f6b)

```

NOTICE: I do not want to see difference what is changed between `6a53778` and `5892f6b`.  

**I want to compare how content of these two commits differ to each other.**
