with holidays), or produce hard copy output.

A function `diary-fancy-display' is provided for use with this
hook; this function prepares a special noneditable diary buffer
with the relevant diary entries that has neat day-by-day
arrangement with headings.  The fancy diary buffer will show the
holidays unless the variable `diary-show-holidays-flag' is set to
nil.  Ordinarily, the fancy diary buffer will not show days for

;; displaying the diary and just visiting the diary file. However,
;; when using fancy diary, calling diary when there are no entries to
;; display does not create the fancy buffer, nor does it set
;; diary-selective-display in the diary buffer. This means some
;; customizations will not take effect, eg:
;; http://lists.gnu.org/archive/html/emacs-pretest-bug/2007-03/msg00466.html
;; So the check for diary-selective-display was dropped. This means the
;; diary will be displayed if one customizes a diary variable while
;; just visiting the diary-file. This is i) unlikely, and ii) no great loss.

      `diary-simple-display' is used.  Use `add-hook' to use
      `diary-fancy-display', if desired, or `ignore' for no display.

  `diary-hook' is run last.  This is used e.g. by `appt-check'.

Functions called by these hooks may use the variables ORIGINAL-DATE
and NUMBER, which are the arguments with which this function was called.
Note that hook functions should _not_ use DATE, but ORIGINAL-DATE.
740
\(Sexp diary entries may use DATE - see `diary-list-sexp-entries'.)
