2) change semantics of lua modifier %x to mean
"Show lua number with hex digits".
We have followed that option (as much as possible). luaconf.h now
defines:
/*
@@ LUA_INTFRMLEN is the length modifier for integer conversions
@* in 'string.fomat'.
@@ LUA_INTFRM_T is the integer type correspoding to the previous length
@* modifier.
** CHANGE them if your system supports long long or does not support
long.
*/
By default, LUA_INTFRMLEN is "l" and LUA_INTFRM_T is long, but the first
can be "ll" or "I64" (or "") and the second long long (or int).
