 The notion of equality on patches isn't completely obvious,
 because it might be structural equality or equality under commutations
 (e.g. for lists of patches).
 So it's better to be explicit about when we need it.
 It moves into PrimPatch instead for now, for V1 and V2 commutation,
 but RealPatch doesn't need it.

This looks good, thanks! 

As a note, it looks like you manually attached the patch text somehow?
It's easier if you just `darcs send`, since darcs will use attachments,
making it easier to apply the patch and test it.
