This does not agree with observation. Probably, Windows 95 should be

I wish to print all information to stdout, except the progress asterisks
"*" and search
paths, and the "\b \b" to remove them. The program dvips distinguishes
console output and
standard output as well, i.e. it seems so at least. How can that be? Or
does the program
have undetermined behavior if you do not redirect stdout?
