add ability to handle directory as a block for #458

[Mukundan314]

I'm not sure if a boolean is the best option here. Currently, my neovim plugins are located in ~/.config/nvim/pack/plugins/opt/*, which falls within my d_nvim block that encompasses the entire ~/.config/nvim directory. However, this directory also contains other files where I prefer the default behavior.

Of course, in this particular case, I could set the directory neovim uses to search for plugins outside of ~/.config/nvim, but that might not always be feasible in other scenarios.

I think having glob patterns or similar mechanisms to specify exactly which of the subdirectories should be treated as a block, would be better?
