[clisp-list] behavior of -x that uses a dribble in clisp-2.33.2 vs. in clisp-2.35

[<ol...@cs...>]

dribble behaves differently between clisp-2.33.2 and clisp-2.35.

E.g., give the command

   % clisp -q -i init.lisp -x '(test)'

where init.lisp contains only

   (defun test ()
     (delete-file "zz") (dribble "zz") (format t "hi~%") (dribble))

For clisp-2.33.2, all output goes to the file zz, which I think is the
correct behavior.

For clisp-2.35, the "hi" comes to the screen and zz contains only the
start and finish of dribble lines, e.g.,
   ;; Dribble of #<IO TERMINAL-STREAM> started 2005-09-16 14:26:53
   ;; Dribble of #<IO TERMINAL-STREAM> finished 2005-09-16 14:26:53

When I run either clisp interactively with

   % clisp -q -i init.lisp

and type (test), the output goes to file zz and the screen.

Is the above difference in behavior a bug or is dribble's behavior
implementation dependent?

I saw this same difference on two systems:
