commit 5efa2ddf62d4876fb62f23b571f4cc0af5885639

    Correctly check buffer mtime when displaying xref matches
    
    This was just a typo: we were checking the modification time of
    current-buffer instead of checking the modification time of the
    passed-in buffer.
    
    This caused matches to not be shown if they weren't present in
    the current in-Emacs state of the buffer.
    
    This was easily reproduced by writing a string to a file outside
    Emacs, then searching for that string with
    e.g. project-find-regexp.  The string would seemingly not be
    found, although in reality it was found, just not displayed.
    
    * lisp/progmodes/xref.el (xref--find-file-buffer):
    Check buf, not current-buffer (bug#70008).
