Sorry for the noise.
We are deprecating the use of ctype inside the Lua core, (See for
instance http://lua-users.org/lists/lua-l/2006-12/msg00155.html for a
discussion about the subject.) Our current replacement does not have
toupper (the obvious implementation as a macro would need another 257
bytes), so we have to handle the lowercase "digits" explicitly.
