New Revision: 197519
URL: http://svn.freebsd.org/changeset/base/197519

Log:
  Make the fuzzer a bit more useful by forcing 7-bit data into it.
  
  Getting valid UTF-8 sequences is quite unlikely, so we'd better just
  convert data to 7 bits and make it extra likely for escape sequences to
  occur.
