Use of 'count' in KVC for NSArray and NSDictionary

[Richard Frith-Macdonald]

I believe the behavior of Key Value Coding in MacOS-X has changed  
compared to the behavior currently implemented in the GNUstep base  
library for classes like NSArray and NSDictionary.  Is there any  
reason why we should not change to maintain/regain compatibility?
The old behavior was to return the count of objects in the  
collection, but the new behavior seems to be to return an array  
containing the results of calling -valueForKey:@"count" on all the  
objects.

As far as I can see, code depending on the old behavior (if there is  
any) could use a category to implement it, but I don't use this stuff  
myself, so I was wondering if anyone had a better idea.
