Add or preserve empty line between CSS rules

Forgive me if this has been asked before but is there a way to keep spacing between CSS rules when formatting?

.login {
    margin-top: 30px;
    padding: 30px;
    background: rgba(255, 255, 255, 0.7);
}

.login.btn {
    border-radius: 0;
    background-color: #5C6166;
    border-color: #4a4a4a;
}

To:

.login {
    margin-top: 30px;
    padding: 30px;
    background: rgba(255, 255, 255, 0.7);
}
.login.btn {
    border-radius: 0;
    background-color: #5C6166;
    border-color: #4a4a4a;
}

This would be so great. I wish js-beautify obeyed sass-lint more explicitly, but this is the only feature that’s giving me a lot of trouble.

@bitwiseman: I opened the new ticket myself since I think it’s highly relevant #1258.
