I'm sorry to say that your pull requests are not mergeable due to whitespace mangling. (Github will tell you that too -- "this pull request cannot be automatically merged.") Can you perhaps run your patches through a whitespace fixing filter before submission? I'm closing this pull req but please reopen with fixed patches. (The pull request page should say "this pull request can be merged", like this one doesn't.)
