Hi kohsuke,

I was using your api, it was great but there is this bug I hope you can fix it soon:
Whenever I call the function GHRepository.getIssues(GHIssueState.CLOSED), it returns a list of both issues and pull requests.

I expect only issue though. Currently my work around is to call getPullRequests then for each issue from getIssues, I search in the whole list of pull requests to see if it is already there. Then I ignore it. But this makes my algorithm runs at O(n*m).

Please fix it soon.
