True. To some extent I removed that comment for reasons that I didn't 
bother to write down in the commit log. First, snprintf has been 
required since C89 and is now universal, and there's little point to 
documenting ancient backward-compatibility problems that no longer 
matter. Second, sprintf can be preferable to snprintf when either will 
do, as sprintf has a simpler API - i.e., nowadays the code avoids 
snprintf for reasons other than the just-removed comment.
