Martin -- still thanks, but, I found a fourth method: NSLayoutManager -setTextContainer:forGlyphRange:
This is embarrassing because I've been pouring over all the text guidelines and class documentation for days now, and didn't see this until after I got your response and tried it. I stumbled on this by accident looking for something else in the NSLayoutManager documentation. So here is a fourth alternative, and seems to work quite well (one test so far). I can imagine circumstances when the \f would be more convenient, and some where the -setTextContainer:forGlyphRange: would be more convenient.
