Off-Topic: does someone know if e-TeX ever considered introducing
a \showboxtofile{foo}<box number> primitive which would do like \showbox
but with
target something else than the log file, and more importantly would not
raise an "error" ?


Goes to the log but you can get the box output without raising an error eg

%%%%%%%%%%%%%%%%
\tracingonline1

\setbox0=\vbox{\hsize=5cm
one

two

{\bf three}

$x=y$
}

\setbox0=\hbox to \maxdimen{\box0}


\bye
%%%%%%%%%%%%%%%%%%

so long as you ignore the spurious underfull hbox around the outside
(this essentially is the same trick \showhyphens uses)
