bug#69894: 29.1; Icalendar export conflict with calendar iso date

[Erwan Hingant]

Hello,

This is the ISO format has a '-'. Proceed with :

(setq diary-file "whatever"
     calendar-date-display-form calendar-iso-date-display-form)

Then, go to calendar and use "i d" on any date or 
(diary-insert-entry) you will see the date inserted in the form 
YYYY-MM-DD. 

Indeed, diary-insert-entry call the calendar-insert-date-string 
which use the format stroed in calendar-date-display-form. You may 
inspect the default proposed value of 
calendar-iso-date-display-form.

Sincerely,
E.
