errors to stdout?

[Andrew Pimlott]

Hugs dumps errors, traces, and other diagnostics to stdout.  It even
has the rather perverse

    #define errorStream      stdout

(except on windows, it appears) so I assume there is a reason for
it.  However, I can't imagine the reason, and it is quite annoying
to me.

I am running "December 2001" hugs on Debian GNU/Linux.  I looked at
the CVS sources, and trace now seems to go to stderr, but errors
still seem to go to stdout (I haven't tried it to be sure).

Would you accept a patch to change everything to stderr?
