Details:

When using (NSKeyValueObservingOptionInitial | NSKeyValueObservingOptionNew)
as option for -[NSObject observeValueForKeyPath:ofObject:change:context:],
GNUstep should use -valueForKeyPath: instead of -valueForKey: to retrieve the
current (initial) value.

With the current implementation, only single keys ("property") are supported
for 'aPath' for this combination of options, whereas key paths
("propertyA.propertyB") are not. This is in contrast to Apple’s
implementation.

A patch is attached.
