I have an patch to TypeScript compiler options to solve issues with different newlines as in this item:
https://typescript.codeplex.com/workitem/258

It adds this option to tsc, and uses it in program.ts / createCompilerHost() / getNewline():
--newLine NEWLINE Use newline: 'dos' or 'unix'.

I've signed the Contributor License Agreement (CLA) and I'm working on test cases but what is the next step to be allowed to push a branch and/or create a pull request?

Thanks to all for TypeScript, and I hoping to eliminate the newline conflicts at the source for mixed development environments of Mac, Linux/UNIX, Windows.
