I noticed that.  The only 'local's shown are the funcs internal ones.  
Could give 'em names unlikely to be used elsewhere.  I've seen that sort 
of thing.  Or is there a better way?  Given the branching and switches, 
I can't think how to do it in one string of pipes w.o. intermediate 
variables.  And variables to hold the switches.

I take it for granted that my colorizing and various condensations and 
formattings are always going to leak, but they're not mission critical 
just efforts to make things look better most of the time. When I find a 
leak I patch it if I can.  Still it's a good thing to do things in the 
most robust way of course.

Well, the paint isn't even dry on that effort I posted. Improvements 
most welcome.  As I have it now, it's just sequential thinking -- first  
get the core functionality, then add the switches (case, etc.) then 
massage the output.  No doubt it can be handled better.  It's C- coding.

Anyway the whole exercise is just a 'cry for help' -- typeset -p (or 
typeset -P) should give us full disclosure.  display-params() should be 
hard coded and, IMHO, accessed via a switch to typeset. Wiser people 
disagree, but that's my two cents.  Nuts, there's already, what? three 
or five functions that sorta attempt to display this information but 
none of them shows it all.  Seems to me a full listing of params with 
*all* attributes and values is core functionality.

And the doc should discuss *all* the attributes in one place. Every last 
one. </whine> :-)
