Empty Section on config file

[dmatos2012]

Hi, This was raised originally in Nushell https://github.com/nushell/nushell/issues/9556,

1. Create sample ini

   [placeholder]
   aws_access_key_id=AAAAAAAAAAAAAAAAAAAAA
   aws_secret_access_key=BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB
   aws_session_token=BBBBBBBBBBBBBBBBBBBBBBBB
   region=us-east-1
   output=json
   [default]
   aws_access_key_id=AAAAAAAAAAAAAAAAAA
   aws_secret_access_key=AAAAAAAAAAAAAAAAAAAAAAA
   aws_session_token=BBBBBBBBBBBBBBBBBBBBBBBB
   region=us-east-1
   output=json

2. Get sections

   let i = Ini::load_from_file("conf.ini").unwrap();
   for (sec, prop) in i.iter() {
       println!("Section: {:?}", sec);

   Outputs:

   Section: None
   Section: Some("placeholder")
   Section: Some("default")

   Expected behavior:

   Sections placeholder and default but not None section.

   Thanks!

It was intended, checkout the comment.

Ah, It is to allow section-less key-value pairs! Thanks for the fast response!
