-   Also worthy of mention is the way traced symbols are managed:  the trace
-   bit is associated with a particular symbol name.  If a symbol is
-   undefined and then redefined, it does not lose its trace bit (in GNU
-   mode).  This is achieved by not removing traced symbol names from the
-   symbol table, even if their value stack is empty.  That way, when the
-   name is given a new value, it is pushed onto the empty stack, and the
-   trace bit attached to the name was never lost.  There is a small amount
-   of fluff in these functions to make sure that such symbols (with empty
-   value stacks) are invisible to the users of this module.  */
