  These were there to work around deficiencies in how Eshell produces
  completions for 'pcomplete-argument' (Eshell passed various non-string
  objects to Pcomplete, which broke things).  Now, Eshell always returns
  a stringified form of the argument, with the original value stored via
  the text property 'pcomplete-arg-value'.
  
  * lisp/pcomplete.el (pcomplete-arg): Revert changes back to a simpler
  form.
