Sorry, I was not as clear as I ought to have been:

By which I mean, if a script or module reports an error by just printing 
a message to the screen:

    print("sorry, an error occurred")

sort of thing. Obviously the interpreter cannot guess which messages 
represent errors in that sense and which are non-error output.

(Of course, a script could format its own error messages, say by using 
terminal-specific colour codes.)
