[elpa] externals/vundo c66abe86e1 2/2: Avoid duplicating vundo--timestamps

[ELPA Syncer]

branch: externals/vundo
commit c66abe86e12671ce46552a38d63a2b635bff23b9

    Avoid duplicating vundo--timestamps
    
    * vundo.el (vundo--record-timestamps): The sorted value of the
      produced timestamp alist is significant, so it should not contain
      duplicates.
