    Add a translator comment about 'KB'
    
    The GLib units policy used to be that 'KB' means 1024 bytes, 'MB' means
    1024 KB, 'GB' means 1024 MB, etc.
    
    Those days are over, but we have a deprecated function that still works
    that way.  It contains the string "KB", marked for translation, which
    has been a source of confusion for translators on multiple occasions.
