Since VEVENT and VTODO are wrapped in `org-icalendar-fold-string', I
think the only place this error may occur is in the preamble created by
`org-icalendar--vcalendar', e.g. in PRODID, X-WR-CALDESC, etc.

The fix is to move the call to `org-icalendar-fold-string' out of
org-icalendar--vevent/vtodo, and instead put it in
`org-icalendar--vcalendar'. Then the line folding will apply to the
whole VCALENDAR instead of just the VTODO and VEVENT. An earlier version
of my CRLF patch actually did something like this.

I can push such a fix over the weekend. Let me know if you'd rather I
send the patch for review here first.
