Commit: Reuben Thomas <address@hidden>

    Remove obsolete comments and commented code from dired-x.el
    
    * lisp/dired-x.el (dired-mark-sexp): Remove a query from 1993 and its
    1997 answer about whether dired-mark-sexp is used.
    * lisp/dired-x.el (dired-buffers-for-dir-exact): Remove this function
    commented out since before dired-x.el was added to RCS in 1994.
