View or edit exception days of a recurrent item
The exception days are presented for viewing/editing as a string of
space-separated dates (in the user-preferred input format). After
editing the string is checked for valid dates, but there is no check
that a date is meaningful (an occurrence day of the item between start
day and until day). Although possible, it is best to add exception days
in the usual way by deletion of occurrences.
