On IRIX and Tru64 UNIX, vsnprintf() returns the number of characters
transmitted, _not_ the number of characters that would have been
transmitted if the buffer were large enough. From error.c:
        va_start(ap, msg);                                      \
        chars = vsnprintf(str, size, msg, ap);                  \
        va_end(ap);                                             \
        if ((chars > -1) && (chars < size))                     \
            break;                                              \
        if (chars > -1)                                         \
            size += chars + 1;                                  \
        else                                                    \
            size += 100;                                        \

This definitely assumes a C99 vsnprintf().
