bug#5261: 23.1.90; diary display

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug.  If you can, give
a recipe starting from `emacs -Q':


1. emacs -q
2. (require 'diary-lib)
3. M-x calendar
4. go to a date with diary entries and hit 'd'

For example:

Friday, 25 December 2009:  Christmas
====================================
Pay rent

The face 'diary' is not applied in the above diary display.

This is a problem because some functions 'secretly' loads diary-lib for
example run-at-timer.


If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
