Subject: Refactor TclScanElement() part of list parsing to take advantage of
 tables constructed for the task of script parsing.  Ought to speed generation
 of string representation of lists, though the effect is likely only
 noticeable on long lists made up primarily of simple elements (not needing
 quoting).
