Log Message:
-----------
Yet more whitespace improvements:
* Do not forcefully break a macro line after closing delimiters,
let it continue when needed.
* In no-fill context, use .No to append text to a macro line when needed.
* In no-fill context, allow .Pf as a child macro when needed.
* Use macro_open() for .Ns, with the proper flags before and after.
