Re: Is terminating null required for Lua strings?

Thank you for the pointers.

This is a non-problem, since there are no API users.

I grepped for strlen and printf and looks like there indeed is some
non-trivial code that expects lua_tolstring to return proper C strings,
like in the str_format function. Will try to figure it out.
