I just made some tests in OPENSTEP 4.2.
It works in a way similar to GNUstep (or the ather way around),
NSMatrix calls setShowsFirstResponder: each time it draws a cell,
and if the cell is the key cell, it calls again with NO after
having drawn it.
I also made a subclass of cell call setShowsFirstResponder:YES before
calling super in drawWithFrame:, and all cells in the matrix appeared
with the dotted line. So, it seems that in OS4.2 setShowsFirstResponder:
is used to tell the cell to display the dotted line or not. The 
documentation is not clear, and it is possible that in MacOSX it
works differently.

I was thinking about removing all those calls and only put them in
a method to change the keyCell and in become/resignFirstResponder in
NSMatrix. Can anybody see any inconvenient for this?
