Well, in his test case, he inserts a short stretch of text
that we can predict, with reasonable confidence, will fit
within a single line box. Therefore, after \unvboxing,
\lastbox will be the line box so created. Of course, this
doesn't generalise, but it does seem to address his specific
needs for this test case, which may suffice.
