New Revision: 335738
URL: https://svnweb.freebsd.org/changeset/base/335738

Log:
  MFC r333157: cmp(1): Provide some long options
  
  These match GNU cmp(1) for compatibility where applicable.
  
  Future work might implement the -i option from GNU cmp(1) to express skip
  either in terms of both files or of the form "SKIP1:SKIP2" rather than
  specifying them as additional arguments to cmp(1).
