I think it makes sense to remove carriage returns on checkin, but I'm not sure it makes sense to add them back on checkout on Windows. Historically, it's been really easy to write LLVM tests that fail when the source is checked out with CRLF. Many Windows developers have noted that LLVM tests fail when using the git config options to accomplish this. So, is there a way to do CRLF -> LF on checkin, but do nothing on checkout?

I think all modern editors on Windows can read LF files, it's just that they tend to prefer to write files out in CRLF, and that's the main source of friction.
