Then I suppose all file attributes are clered with this save 
operation? The actuall process of saving (if an old file exists) 
would then include getting old attributes with fileAttributesAtPath, 
then writeRTFDToFile and lastly changeFileAttributes back to the 
previous attributes (but with the new modification date). However, I 
think this feels strange, but since you observed -[NSString 
writeToFile] work similar, it is perhaps a normal behaviour.
