avoid using NULL in varadic function for cmdline parsing
cppcheck reports: (portability) Passing NULL after the last typed argument to a variadic function leads to undefined behaviour. We don't ship on any platform which has this as undefined behaviour through – or it would be pretty well defined "bad" behaviour which always works, so even through UB is a trigger word, its hardly noteworthy as a change (and as a bonus the scanners of gcc/clang don't consider it UB). The commonly accepted method of fixing that seems to be (const char*)NULL, but it is in fact much simpler to just switch to the varadic functions C++ provides resolving the warning and reducing code.
