 The style is tested without a tag by the function completing
 pathnames in order to determine whether to ignore the names of
 directories already mentioned in the current word, or the name of
 the current working directory.  The value must include one or both
 of the following strings:

 parent
      The name of any directory whose path is already contained in
      the word on the line is ignored.  For example, when completing
      after foo/../, the directory foo will not be considered a
      valid completion.

 pwd
      The name of the current working directory will not be
      completed; hence, for example, completion after ../ will not
      use the name of the current directory.

 In addition, the value may include one or both of:

 ..
      Ignore the specified directories only when the word on the
      line contains the substring '../'.

 directory
      Ignore the specified directories only when names of
      directories are completed, not when completing names of files.

 Excluded values act in a similar fashion to values of the
 ignored-patterns style, so they can be restored to consideration by
 the _ignored completer.
