I wonder if this is the correct interface. I often use case 1 above,
but nearly always with a single path. When I use diff with two paths
I nearly always want case 2. In fact one of the things I want to do
is not supported: namely to diff my working copy against a "branch".

Perhaps a better interface would be

 svn diff [-r N[:M]] TARGET
 compares different revisions of TARGET

 svn diff [-r N] TARGET1[@N] TARGET2[@M]
 compares TARGET1 against TARGET2

I can always get the current 'svn diff PATH1 ... PATHN' behaviour by
invoking 'svn diff PATH1' ... 'svn diff PATHN'.
