Hi,

As contrived e.g: if I have in my "workspace" sub directories mostly git repositories, but some not and if I exec, "for d in */ ; do (cd $d && git check-ref-format --branch @{-1}); done" then I get 3 possible responses.

git version: 2.13.0
1. Valid branch name
2. fatal: '@{-1}' is not a valid branch name
3. fatal: BUG: setup_git_env called without repository

git version 2.13.2.915.ga9c46e097
1. Valid branch name
2. fatal: '@{-1}' is not a valid branch name
3. BUG: environment.c:178: git environment hasn't been setup

best marko
