Yes, that particular function can be fixed, but unfortunately there are several 
other functions like that, and they can't all be fixed so easily. I wrote a 
simple three-line patch to fix them all, but if you'd rather do it the hard way 
and "audit the sources from now to eternity" to make sure the hard way continues 
to be done correctly everywhere in the future, please feel free to do that. Or 
if you want to fix just message_to_stderr but not the other occurrences of the 
problem, please feel free to do that too. Either of these things would improve 
over what is in master now, although they wouldn't be as good as the three-line fix.
