Rustdoc source code output dislikes windows line endings

Image says it all really, running rustdoc on files with windows style line-endings inserts (or doesn't strip?) additional newline characters, screwing up alignment with the line numbers:

This only seems to affect regular comments, doc comments are fine.

Edit: since it's not really obvious from the image due to the nature of the bug, it should look like this:

// Test comment
pub fn test() {}

// Test comment
pub fn test2() {}

// Test comment
pub fn test3() {}
