Dimitry Andric 2f214595bc Ensure showbase does not overflow do_put buffers Summary: In https://bugs.freebsd.org/207918, Daniel McRobb describes how using std::showbase with ostreams can cause truncation of unsigned long long when output format is octal. In fact, this can even happen with unsigned int and unsigned long. To ensure this does not happen, add one additional character to the do_put buffers if std::showbase is on. Also add a test case.
