Fix ini example

[fabiim]

• Support white space around equal separator in INI files

The grammar as it was failed to support white space around name=value
entries in an INI file. I faced these errors:

    thread 'main' panicked at 'unsuccessful parse: Error { variant: ParsingError { positives: [char], negatives: [] }, location: Pos(8), line_col: Pos((1, 9)), path: None, line: "username = noha␊", continued_line: None }', src/libcore/result.rs:997:5

• Finish file with new line

  As it stands the current grammar does not parse the given file
  correctly. Not sure how to fix it in the grammar otherwise I
  would.

    thread 'main' panicked at 'unsuccessful parse: Error { variant: ParsingError { positives: [char], negatives: [] }, location: Pos(223), line_col: Pos((15, 17)), path: None, line: "interface = eth1", continued_line: None }', src/libcore/result.rs:997:5

Whitespace in INI files is addressed in the "Whitespace" section near the end of the chapter.

Can I ask which steps you took to get the parse error without reaching that section? Maybe you stopped right at the beginning of "Program initialization"?

Evidently the ordering is confusing. Maybe it's possible to restructure that chapter.

I just identified one problem with the chapter here.
