Using the "_r" suffix for async-signal-safe functions is a bad idea,
because other "_r" functions are not async-signal-safe, but merely
multithread-safe, and our snprintf() and vsnprintf() are already
multithread-safe.

If we'd like to provide an async-signal-safe variant of function,
we should use a suffix other than "_r".
