Even if it didn't exist in Cocoa, it isn't an incompatible change where we would
solve a particular problem in an incompatible way - we'd simply extend the basic
concept to be more intelligent and behave more as people would expect it - to be
able to use attributed and nonattributed strings interchangeably in controls.
The only difference for an app programmer would be: "this one's a plain string
and this one's a fancy string".

I've attached a patch to NSCell.m (diff'ed against the latest CVS version) which
should do it.
