 Great!  Your proposal looks good to me in principle, however you need to 
factor in SPECIAL having been set by `#' somehow as `number' will respect 
it.  I suggest using the same field width calculation that `pointer' uses 
for `default_width' (sans the type used with `sizeof' of course, that is).
