compare_output() fails on Windows due to different line endings

[fkohlgrueber]

I described the issue in rust-lang/rust before (link).

As noted in that issue, all one needs to do is to create a .gitattributes that forces LF line endings on checkout.

Do you agree that a .gitattributes file should be added to this repo? It might also be a good idea to make this information part of the docs.

I can open a PR if you want me to.

Hi @fkohlgrueber I totally missed this issue being posted, I'm sorry!

Do you agree that a .gitattributes file should be added to this repo? It might also be a good idea to make this information part of the docs.

If that's all it takes to fix it, I have no problem with it, but I don't really have a good way of testing it myself.

I can open a PR if you want me to.

Please do :-)
