It would seem that the string library doesn't yet completely like
embedded null characters in patterns. In particular, the following
code doesn't give the expected result:

Lua 5.2.0 (alpha)  Copyright (C) 1994-2010 Lua.org, PUC-Rio
> return string.find("\0\0","\0.")
nil

I believe that this is caused by the following line in lstrlib.c,
which causes patterns with no special characters prior to the first
embedded null character to be treated as plaintext.

strpbrk(p, SPECIALS) == NULL)) {  /* or no special characters? */
