New Revision: 189104
URL: http://svn.freebsd.org/changeset/base/189104

Log:
  Remove redundant code in printf() and vprintf().
  
  printf() and vprintf() are exactly the same, except the way arguments
  are passed. Just like we see in other pieces of code (i.e. libc's
  printf()), implement printf() using vprintf().
