Rugged::Diff::Line#hunk always returns nil

[mmozuras]

Rugged::Diff::Line#hunk or (#owner) seems to always returns nil. How to reproduce:

irb(main):001:0> require 'rugged'
=> true
irb(main):002:0> repo = Rugged::Repository.new('.')
=> #<Rugged::Repository:70098604661600 {path: "/Users/mindaugasmozuras/Projects/rugged/.git/"}>
irb(main):003:0> diff = repo.diff('HEAD', 'HEAD~1')
=> #<Rugged::Diff:0x007f8234db3400 @owner=Rugged::Tree>
irb(main):004:0> diff.each_line.map { |line| line.hunk.class }
=> [NilClass, NilClass, NilClass, NilClass]

Seems to be introduced with this commit. /cc @arthurschreiber

Do you need this functionality, or can I remove the #hunk method. It's basically a leftover.

[arthurschreiber]

Actually, I'll have to remove it, because #each_line does not generate hunk information, and thus it won't be available in all cases. That's why I removed it in the first place. Thanks for pointing this out! 😄

[mmozuras]

@arthurschreiber no problem 😄

[arthurschreiber]

Does #393 look good to you?

[mmozuras]

@arthurschreiber yes, it does.
