That is asking the same question as you. As you noted, there isn't a solution. It seems a fundamental limitation of TeX. Hboxes do not have any kind of stretch derived from their contents. (It might be interesting to consider how a replacement system might do things differently, not that that helps us with texinfo.tex. I imagine that the hbox could be set in a range of widths to obtain a badness at each width, then this badness-width function would feed into the paragraph optimization somehow.) > but the accepted answer seems incorrect, or not answering the > general issue.
