The grunt build process already forces UNIX line endings. In this case I built in a branch and pushed to git. Then auto-merged the pull request and pulled to local master. After the pull to local master bitaddress.org.html had DOS line endings.
I updated the process I use to sign to re-build before sign to enforce the UNIX line endings so even in a scenario like above I will avoid this in the future.
That verified.
