fancy diary display and longlines-mode

[Stephen Berman]

With diary files that have longlines-mode enabled, fancy diary display
truncates all but the first line of a wrapped entry.  To reproduce, do
the following:

1. emacs -q
2. C-x C-f ~/test-diary (e.g.) and enter a long diary entry without a
line break, e.g.: "Apr 21, 2006 14.15 This entry tests whether fancy
diary display works with long lines displayed in longlines-mode." and
save it.
3. M-: (add-hook 'diary-display-hook 'fancy-diary-display)
4. M-x calendar
5. Put the cursor on the calendar date of the entry you just made and
type `D' and enter the name of the diary file you just saved: you get
a fancy diary display of the entire entry as a long unbroken line.
6. Click on the fancy diary entry with mouse-2 to visit the diary file
and type `M-x longlines-mode': this shows the entry with line breaks
(e.g., the above entry is broken after `works'.
7. Repeat step 5: now the fancy diary display shows only the first
line of the entry (in the above, ending after `works').
