Using `bat` would result in the command being a nested list.
eg. using `:Telescope plaents` with `bat` installed
```
{
"bat",
{ "--pager", "less -RS" },
"--style=plain",
"--color=always",
"--paging=always",
"--",
"/home/jt/projects/telescope.nvim/data/memes/planets/earth",
}
```
This would cause `vim.fn.termopen` to throw an error as the command is
expected to be a flat list or string.
