Log Message:
Solve the problem that _ did not expand in verbose mode, and _|_ and
^C had no parent.  Basically, we followed the result chain pointer
too far.  Now, the getResult() routine stops at the last expression
before the _, ^C, or _|_, and the pretty-printer must take a quick look
(peekResult()) down one link of the chain to decide how to display
the expression.
