Nothing, actually ;)
I did my best to establish good upper bounds (with your help at least 
one time, I seem to recall) but, nevertheless, I'm still finding 'safer' 
the built-in logic present in snprintf and I like the simplifications 
made possible by a snprintf unconditionally available on any platform 
(both C99 e C90).

P.S. Of course, in the long term Jerry will format floats too without 
relying on s[n]printf...
