git diff between working copy and branch base

问题

I can compare the tip of master and my working copy with

git diff master

I can compare the tip of the current branch with its merge base from master with

git diff master...

Is the a git diff command to compare the merge base of the current branch and the working copy?

If you current branch is not master, you can try in a bash shell:

git diff $(git merge-base --fork-point master)

If uses git merge-base with --fork-point:

git merge-base --fork-point <ref> [<commit>]

Find the point at which a branch (or any history that leads to <commit>) forked from another branch (or any reference) <ref>.
This does not just look for the common ancestor of the two commits, but also takes into account the reflog of <ref> to see if the history leading to <commit> forked from an earlier incarnation of the branch <ref>.
