  Use 'printf' (POSIX issue 4) instead of 'echo -n', for portability.
  
  The problem with using 'echo -n' is that it is not portable.  While BSD systems
  required that the '-n' option be removed and interpreted, System V required
  that all strings should be echoed with no interpretation of options.  This
  fundamental difference of behavior means that it is never possible to use the
  '-n' flag to echo in tests which are meant to be portable.
  
  In this case, on Mac OS X 10.6, the /bin/sh shell builtin 'echo' uses the
  System V semantics of the command, and thus the SHELL test failed on that
  platform.
