"git check-attr" when (trying to) work on a repository with a working tree did not work well when the working tree was specified via --work-tree (and obviously with --git-dir). The command also works in a bare repository but it reads from the (possibly stale, irrelevant and/or nonexistent) index, which may need to be fixed to read from HEAD, but that is a completely separate issue. As a related tangent to this separate issue, we may want to also fix "check-ignore", which refuses to work in a bare repository, to also operate in a bare one. * jc/check-attr-honor-working-tree: check-attr: move to the top of working tree when in non-bare repository t0003: do not chdir the whole test process
