### Problem / Steps to reproduce

I have this in my `.vimrc` (found here for the buffers command: https://github.com/junegunn/fzf.vim/issues/1583):

```vim
let g:fzf_vim = {}
let g:fzf_vim.buffers_options = ['--keep-right']
let g:fzf_vim.history_options = ['--keep-right']
```

This works for the `:Buffers` command but not for the `:History` command. Is `history_options` wrong?

The documentation looks like it should work for any command:
