Another request, as mentioned in earlier posts (shutting off the parse
features) a parse/white switch that turns off the automated comma, quote and
semicolon parsing rules eg;
parse/white none {Hello world, "this too" is an example;} ;will return...
==["Hello" "world," "this" "to" "is" "an" "example;"]
currently it returns...
["Hello" "world" "this too" "is" "an" "example"]
I've included Joel's response below.

Suitable redefinitions of GOOD-ONES and OTHERS will let you keep or
discard whatever characters you wish, of course.
