13/* Bugs to file:
14
15¥ any trailing spaces: -> exception for +[NSCalendarDate dateWithNaturalLanguageString]:
16 > NSCalendarDate dateWithNaturalLanguageString: '12 '
17 format error: internal error
18
19¥ NSDate natural language stuff in NSCalendarDate (why?), misspelled category name
20¥ NSCalendarDate natural language stuff behaves differently from NSDateFormatter (AM/PM has no effect, shouldn't they share code?)
21¥ NSDateFormatter doc class description gives two examples for natural language that are incorrect, no link to NSDate doc that describes exactly how natural language dates are parsed
22¥ NSTimeFormatString does not include %p when it should, meaning that AM/PM is stripped yet 12-hour time is still used
23¥ NSNextDayDesignations, NSNextNextDayDesignations are noted as 'a string' in NSUserDefaults docs, but maybe they are actually an array, or either an array or a string, given their names?
24¥ "Setting the Format for Dates" does not document how to get 1:15 AM, the answer is %1I - strftime has no exact equivalent; the closest is %l. strftime does not permit numeric prefixes. It also refers to "NSCalendar" when no such class exists.
25¥ none of many mentions of NSAMPMDesignation indicates that they include the leading spaces (" AM", " PM"). In "Setting the Format for Dates", needs to mention that the leading spaces are not included in %p with strftime. But if you use the NSCalendarDate stuff, it appears %p doesn't include the space.
26¥ descriptions for %X and %x are reversed (time zone is in %X, not %x)
27¥ too hard to implement date-only or time-only formatters
28¥ should be able to specify that natural language favors date or time (10 = 10th of month, not 10am)
29¥ please expose the iCal controls!

If we could get the active text field somehow via public API (guess we could use controlTextDidBegin/controlTextDidEndEditing) then we'd not need to overload the update sender for this purpose. Or, I guess, we could use another method other than update. It should not be this hard to implement what is essentially standard behavior. Sigh.
