[dev] iCalendar parsing problem

[Justus Pendleton]

I tried using one of the shared calendars on www.icalshare.com with 
Kronolith with little success; the calendar is 
http://ical.mac.com/lilscoy/smallville.ics.  After a little digging, the 
problem seems to be with a change made in version 1.37 of iCalendar.php 
in the framework.  The regexp for finding subcomponents was changed from 
ungreedy to greedy, which looks wrong to me.  When I took a look at the 
intermediate $data values during the parsevCalendar loop each successive 
iteration included not only the next subcomponent but also all previous 
subcomponents.  When I changed the regexp to be ungreedy again, this was 
fixed.  If that regexp is greedy it seems to me that it won't find the 
appropriate matching END:VEVENT tag.
