bug#8392: Diary entries does not work with ISO date format

[Glenn Morris]

> I have configured my .emacs file to use ISO dates format

No you haven't. The only relevant setting in your attached .emacs is one
for calendar-date-display-form. This just affects how dates are
*displayed*, nothing else. There are other things you need to set,
notably diary-date-forms. But don't bother setting either of those by
hand, just customize calendar-date-style to `iso' instead. That will set
all the necessary variables.
