bindings of *DEBUG-IO*

[nathan@bristol.st.com]

Hi,
I'm getting confused about the binding of *DEBUG-IO* when
using clisp non-interactively with the -x command line option.
It appears that *DEBUG-IO* becomes a two-way-stream, rather than
a synonym for *TERMINAL-IO*. However I can't find this documented
anywhere in either the manual page describing -x, or the
implementation notes, grepping the doc directory left me none the wiser.

This is probably the correct thing to do -- after all
if you're not interactive you don't want to prompt the user for
continues after CERROR.

So my question is what are the stream binding differences between
interactive and -x usage? Is my supposition correct and is *DEBUG-IO*
a null input stream when non-interactive?

thanks in advance.
