Thanks, Michael, that works great!

Just out of interest: why does \savewidth create a newline
if there's more text on the same line,
(like this:
   \savewidth{start of line} and some more text
)
while \addtosavewidth does not? The difference is the \hskip in front
of the \copy0%; if I add \hskip0pt in front of the the \copy in
\savewidth, there's also no newline -- but how does that make sense?

Michael
