Lua 5.2 has this layer. According to ISO C, "If a conversion specifier
is not one of the above,the behavior is undefined", and undefined
behavior includes crashing. It is a really stupid behavior, but it is
"legally correct" :( It is also a pity, because os.date will no longer
accept OS-specific extensions.
