How about this?  It skips PM_RO_BY_DESIGN for any parameter not
declared in the same scope where "typeset -p" is being run.  This
means that in addition to displaying parameters declared private,
it'll show cases where "local +h" has been used to shadow a special.

No doc included in this patch, but we should probably mention
somewhere that "typeset -p" no longer displays values for the special
parameters $!, $#, $-, $*, $@, $$, $?, $ARGC, etc. (unless "local +h"
per above)  This is actually a change in 5.9 vs. 5.8 that was not
included in the NEWS file.  Should it also be in the Doc?
