indexing vim.cmd requires neovim version greater than 0.8.0

[kevin820606]

The version of Neovim provided by Debian and Ubuntu is currently 0.7.2, which may not fully support the use of the "vim.cmd." notation. Perhaps this is worth noting for those guys who want to try your vimrc setup.

@kevin820606 You can get latest version of neovim on Ubuntu or Debian by building neovim from source.

Alternatively, just download the latest debian package from the nightly build. https://github.com/neovim/neovim/releases/tag/nightly
