Bernt, I suspect that you cannot decide the question with a simple experiment like this, but I have no counterexample to offer. However, Knuth warns explicitly (p.91 of my version of the TeXbook, paperback 19th printing, Oct. 1990) that "...you shouldn't leave any blanks next to the ~, since they will count as additional spaces." It may well be that TeX's line-breaking algorithm does the right thing in the example, but when push comes to shove in a *really* complicated situation, it might be forced to choose the space after the tilde to break the line at.
