Summary: Missing Docs for String Representation of List Elements

Initial Comment:
There is no documentation for how Tcl generates the string representation 
of list elements. When is an element brace-quoted? When are braces 
backslashed?

From IRC:

   <dgp> IIRC, Tcl's string rep. production rules for a list element are:
   <dgp> 1) no quoting, if that's safe.
   <dgp> 2) Brace quoting, if no imbalance produced
   <dgp> 3) backslash quoting, otherwise.
   <dgp> that's it.  No "mixed modes" produced.

This should be documented somewhere.
