Code:
awk 'BEGIN { len = 80 }
   length <= 80 { print; next }
   {
     print substr($0,1,len)
     $0 = substr( $0, len + 1)
     while ( length >= len - 4 ) {
        printf "    %s\n", substr($0,1,len - 4)
        $0 = substr( $0, len - 3)
      }
     if ( length ) printf "    %s\n", $0
   }
' "$FILE"

I know it doesn't add 4 spaces before the newline but if you basically want to get max 80 chars per line and wrap the rest, this will do that:

Code:
fold <input_file>
