Neovim: Provide command line arguments of neovim

[eyalk5]

Hi,

It would be nice if neovim would provide the exact arguments that were used to run it.
I mean if I called it "nvim -u NONE" , a variable would contain "-u NONE".

For example, we can decide if we want to load last unsaved workspace depending on the args.

Note that there's argv() already, but a bit different.

As for a new feature it would be best to have a list for it, instead of a string then I think.
