- - check-attr: move to the top of working tree when in non-bare repository

+ Will merge to 'next'.
 
- "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

- need to be fixed to read from HEAD, but that is a completely
- separate issue.  As a related tangentto 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.
