Summary view for the repository located in the working directory and the one linked to the current buffer

[iamFIREcracker]

Sometimes I just want to pop open the summary view and have it show information about the repository in the current working directory and not the one linked to the current buffer. Is there an idiomatic way to achieve that?

I am currently using: :edit .git/index, and I am quite happy with it; however, fugitive would spit the following warning, and I am curious to understand if there is a repacement for that, or if the workflow was discouraged altogether.

Here is the warning:

fugitive: Direct editing of .git/index is deprecated

The thing that is changing is the status buffer is moving from .git/index to a fugitive:// URL. URLs aren't relative to the current working directory, so there's no drop in replacement. Best you could do is wrap it in a command:

command! -bang -bar GCWDStatus
      \ if empty(FugitiveExtractGitDir(getcwd())) |
      \   echoerr 'Not in a Git repository' |
      \ else |
      \   exe 'edit<bang>' fnameescape(FugitiveFind(':', FugitiveExtractGitDir(getcwd()))) |
      \ endif

I don't mind custom commands, so I am happy dropping that in my vimrc. Thanks lots!
