Shifting a block of text

[fatiparty]

Trying to adapt the following function to use all arguments rather than just 
the first one.
The code should introduce nc spaces ahead of the start of each argument passed. 
Each shifted argument must be on  new line.  The first argument ins numeric, 
defining
the amount of shift.

shifted-block ()
{
 if (( $# == 1 )); then
   nc=0 ; arg="$1"
 elif (( $# >= 2 )); then
   nc="$1" ; arg="$2"
 else
   nc=0 ; arg="$1"
 fi

 nw=$(( nc + ${#arg} ))
 printf "%${nw}s\n" "$arg"
}
