[nicojs]

See https://help.github.com/articles/dealing-with-line-endings/

After a pull: you can reset line endings locally to unix using these steps:

• Save your current files in Git, so that none of your work is lost.

git add . -u
git commit -m "Saving files before refreshing line endings"

• Remove every file from Git's index.

git rm --cached -r .

• Rewrite the Git index to pick up all the new line endings.

git reset --hard
