In 7.2 on windows the EOL marker in OpenSSL seems to have changed to \r\n instead of \n only.

This can be fixed/handled in userland but in all previous versions this was the same on different OSes.

I'm not sure if this is a kind of bug or should simply be communicated in the documentation/migrating guide.
