While I had no problems with that in the past, I just spotted the pattern of the matching does treat the first \0 as the end of the pattern. I hope I did not over-read a subtile area of the Lua manual that points out embedded zeros are not allowed in the string library pattern matching so that those examples should work as I would expect:
See the character class %z in the Lua manual which matches the nul character.
