Way to make dq to work outside of fugitive buffer?

[xiaochuanyu]

Is there some way of mapping dq which cleans up diff buffers for me to work outside of the fugitive buffer?
After reading I tried below after reading #1425 without success:

nmap <leader>gg <Plug>fugitive:dq

In my workflow I run :Git difftool -y to look at diffs for all my files. Then, when I'm done looking I'd like to just do <leader>gg anywhere to clean up all the diff buffers (and ideally those extra tabs too).

The underlying function is public so you can call it directly:

nmap <silent><script> <Leader>gg :<C-U>call fugitive#DiffClose()<CR>

This won't touch other tabs; Fugitive doesn't have anything for that.
