If you look closer, you'll see that -- except in one place -- these functions
are used on normal, 0-terminated, C strings. Here is a complete list of uses
of these functions in Lua 4.0a:

lauxlib.c	strchr
lauxlib.c	strcmp
lauxlib.c	strncpy
lbuiltin.c	strcat
lbuiltin.c	strchr
liolib.c	strcat
llex.c		strcpy
lstrlib.c	strncpy
lstrlib.c	strpbrk
lvm.c		strcoll

The only place I could find in a quick scan of these files that uses a str*
function on Lua strings was the use of strcoll in lvm.c, but there the code
very carefully handles embedded zeros.
