Insread of building one big format string:

   printf("<-s fmt><value fmt><-e fmt>", name, value)
it keeps them separate:
   printf("<-s fmt>", name)
   printf("<value fmt>" value)
   printf("<-e fmt>", name);

This makes the -s -e formats much easier to understand, and leads to
simpler formats needed, like:

old format                      new format
-------------------             -----------------
-s '%.0s'                       -s ''
-e '%1$s'                       -e '%s'
