You're missing a new line :-)  Seriously though, there are any number of 
ways to do the job, some longer and more obscure than others.   If you 
don't have printf and echo -n you can still do it:

   echo $(echo "# Configured with:"; for i in "$0" "$@"; do echo "'$i'"; 
done)

and there are ways of using 'tr -d' as well.  And, I'm sure, many 
others.   We should have a Holiday Competition for the most obscure :-)
