For anybody reading this who has been looking for a way to get involved in 
OIIO... this is an ideal case of a "good first issue" -- it is literally a 
one-line fix.

If you want to give it a try, please say so here so that there aren't 10 people 
trying to do the same fix (I wish) or that I don't do it instead, thinking that 
nobody else will.
