I think Duy meant

  git diff A/$(git symbolic-ref --short HEAD)

i.e. "the branch with the same name as the current one, but on a
different remote". If this is the question, then it is a Git thing more
than a shell one.

The A/@ could make sense, but I'm wondering whether we're taking the
direction of implementing some kind of Brainfuck dialect in Git revision
specifiers. I'm not sure we want to add more special characters here and
there with subtly different meanings (@ = HEAD, @{1} = HEAD@{1}, A/@ =
A/$(git symbolic-ref --short HEAD)).
