Bug#560789: pbuilder: output uses CAPITAL FONTS

[Loïc Minier]

 Hit this a good number of time today; sometimes happens when aptitude
 installs build-deps, sometimes when pbuilder calls apt-get install
 fakeroot, sometimes not at all.  I did not manage to strace a broken
 apt-get, so it could very well be a race condition.

 Since the ouput is broken between apt-get's output and dpkg output, my
 best suspect so far is APT's terminal handling, perhaps in this code:
      // if tcgetattr does not return zero there was a error
      // and we do not do any pty magic
      if (tcgetattr(0, &tt) == 0)
      {
         ioctl(0, TIOCGWINSZ, (char *)&win);
         if (openpty(&master, &slave, NULL, &tt, &win) < 0)
         {
            const char *s = _("Can not write log, openpty() "
                              "failed (/dev/pts not mounted?)\n");
            fprintf(stderr, "%s",s);
            fprintf(term_out, "%s",s);
            master = slave = -1;
         }  else {
            struct termios rtt;
            rtt = tt;
            cfmakeraw(&rtt);
            rtt.c_lflag &= ~ECHO;
            // block SIGTTOU during tcsetattr to prevent a hang if
            // the process is a member of the background process group
            // http://www.opengroup.org/onlinepubs/000095399/functions/tcsetattr.html
            sigemptyset(&sigmask);
            sigaddset(&sigmask, SIGTTOU);
            sigprocmask(SIG_BLOCK,&sigmask, &original_sigmask);
            tcsetattr(0, TCSAFLUSH, &rtt);
            sigprocmask(SIG_SETMASK, &original_sigmask, 0);
...
