unable to provide cwd to vim-fugitive commands

[danrasmuson]

All vim fugitive commands use the cwd of the current buffer. This is convenient and helpful except when scripting.

* This command (along with all other commands) always uses the current buffer's repository, so you don't need to worry about the current working directory.

I have a desire to provide a different cwd to command such as...

vim.cmd("vertical Git log cwd=/directory/other/then/buffer_cwd")

But this does not appear possible.
