using cvs diff

[Bill Medland]

I can't see it in TFM

I thought I was keeping an eye on what patches had actually been applied to
the wine source (especially to see if mine had) by using "cvs diff wine". 
It seemed to be working but I now realise it wasn't.  I guess it was
diffing my local code against the corresponding revisions.

How do I diff my current set of code against the current cvs?
