function `mark-included-diary-files' as part of `mark-diary-entries-hook'.

;; The first version of this also checked for diary-selective-display
;; in the non-fancy case. This was an attempt to distinguish between
;; 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 switch on
;; 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 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.

After the list is prepared, the hooks `nongregorian-diary-listing-hook',
`list-diary-entries-hook', `diary-display-hook', and `diary-hook' are run.
These hooks have the following distinct roles:

    `nongregorian-diary-listing-hook' can cull dates from the diary
        and each included file.  Usually used for Hebrew or Islamic
        diary entries in files.  Applied to *each* file.

    `list-diary-entries-hook' adds or manipulates diary entries from
        external sources.  Used, for example, to include diary entries
        from other files or to sort the diary entries.  Invoked *once* only,
        before the display hook is run.

    `diary-display-hook' does the actual display of information.  If this is
        nil, simple-diary-display will be used.  Use add-hook to set this to
        fancy-diary-display, if desired.  If you want no diary display, use
        add-hook to set this to ignore.

    `diary-hook' is run last.  This can be used for an appointment
651 652
        notification function.
