  p_snprintf: no need for arguments to a format `snprintf` requires a _format_ but does not require _arguments_ to the format. eg: `snprintf(buf, 42, "hi")` is perfectly legal. Expand the macro to match. Without this, `p_sprintf(buf, 42, "hi")` errors with: ``` error: expected expression p_snprintf(msg, 42, "hi"); ^ src/unix/posix.h:53:34: note: expanded from macro 'p_snprintf' ^ /usr/include/secure/_stdio.h:57:73: note: expanded from macro 'snprintf' __builtin___snprintf_chk (str, len, 0, __darwin_obsz(str), __VA_ARGS__) ```
