The docs say:


  This shows two dashes (‘--’) if the buffer displayed in the window has
  the same contents as the corresponding file on the disk; i.e., if the
  buffer is unmodified.



AFAIK, a file-visiting buffer is not marked as modified when text
properties are applied to it. This makes sense, because text properties
are not part of the contents of the corresponding file.
