Re: check if one branch contains another branch

I assume that:

git branch -d  xxx

will prevent a delete if the current branch doesn't contain xxx..
I don't want to have to checkout  origin/dev in order to run that command,
that's one part of the problem

In that case, don't you want to learn, not just if your 'dev' has
anything that is not merged/accepted by origin/dev, what commits
in 'dev' are not yet merged in origin/dev?

 $ git log origin/dev..dev

would show them.
