Subject: Re: Returning duplicate values from Dir.glob

Hi guys,

Thank you for great responses!

I also double-checked that Perl's glob also
returns duplicates in this test case.

Given the great experience with spec-related questions, I exepect
there will be more of them here in the future! :)

Also, we really need a proper bug tracking to report spec/rubyspec
related issues reliably.

Thanks,
  --Vladimir
