[Emacs-diffs] master f7c4bad: Ensure button-get works in any buffer

branch: master
commit f7c4bad17d83297ee9a1b57552b1944020f23aea

    Ensure button-get works in any buffer
    
    * lisp/button.el (button-get): Previously we assumed that button-get
      was called in the buffer containing the button.  In other buffers,
      button-get always returned nil.  Fix this by passing the relevant
      buffer from the marker.
