Thanks Junio, I forgot about merge-base. I'll create some aliases for now:

    # Diff Branch
    db = "!f() { : git diff ; git diff $(git merge-base @{upstream}
HEAD) ; }; f"

    # Diff Tool Branch
    dtb = "!f() { : git diff ; git difftool -d $(git merge-base
@{upstream} HEAD) ; }; f"

Since I use push.default = current, I always keep my upstream set to
the parent branch (origin/master, origin/release/1.2.3, etc). So in my
case these aliases work, but probably not for other push.default
settings like 'upstream'.

Would be nice in the future to have another revision specification
like @{wc} for "HEAD + working copy". I guess this technically isn't a
revision, but something along those lines. Or maybe just an
--include-wc for diff or something.

Thanks again!!
