Re: `string.unpack` 's bug in option `z`

[actboy168 <actboy168@...>]

In struct  library , option `s` means read a zero-terminated string.So the same test is

local struct = require 'struct'

print(struct .unpack('s', 'ABC'))

True, but that error is:
   bad argument #1 to 'unpack' (invalid format option 'z')
I.e. the option 'z' is an addition available in the Lua 5.3 library version.
