New Revision: 333157
URL: https://svnweb.freebsd.org/changeset/base/333157

Log:
  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).
  
  MFC after:	1 month
