OK.

Well, there is extra redirection in sayBrightlyNT. This redirection
probably does not affect sayTeX (at first I thought that it may).
We also use Lisp synonym streams and bindings of Lisp
'*standard-output*'. Hopefully all this mess do not affect
your change, but one have to be careful.
Which situations: output to file, paste generation, dumping algebra
output to a file (while getting output to console).
So, after second look your change probably is correct, but needs
some checking.
