    cpdup - Enhance -X operation
    
    * Enhance -X operation.  When the cpignore file is specified as an
      absolute path, it may contain wildcards which match against the
      concatenated source path and directory element (as specified in the
      source), instead of just match against directory elements.
    
    * Thus an absolute cpignore file may contain full paths and wildcards.
      For example, if you:
    
      cpdup -X $cwd/mycpignore /tmp /fubar
    
      And $cwd/mycpignore (specified with an absolute path) contains:
    
          /tmp/xyz/swap*
    
      Then cpdup will not copy files that match against /tmp/xyz/swap*.
    
      If you specify a relative path for the cpignore file, or use the
      -x option (instead of -X cpignorefile), operation remains as before
      and only matches against the directory element.
