bug in comparison of NSCells

[Benhur Stein]

Hi!
With the recent change that obsoleted -compare: in NSObject, NSCells 
that are
text cells, containing attributed strings instead of strings are 
logging
a warning when compared. Should the -compare: method in NSCell be 
extended
to include the comparison of NSAttributedStrings, or 
NSAttributedString be
extended to include a -compare: method (which I think would be 
better, even
if not in Openstep)?
