This has already moved away from the original "I want to know on which branch other worktrees are working" feature, but while we are expanding the edges...

I wonder what you want to see when a detached HEAD deviated from its initial position (i.e., when we say "HEAD detached from", not "HEAD detached at", in "git status" output). Would we still want to show the "--decorate" list of existing refs for the original position?

    $ git checkout --detach master
    $ git status | head -n1
    HEAD detached at 3bd955d269
    $ git checkout --allow-empty -m empty
    $ git status | head -n1
    HEAD detached from 3bd955d269
    $ git reset --hard HEAD^
    $ git status | head -n1
    HEAD detached at 3bd955d269

If we add "(master)" after 3bd955d269 in the above illustration, I wonder if it makes it too misleading.
