It works. I'd like to add

          3. svn diff URL1[@N] URL2[@M]

             Shorthand for 'svn diff [-rN[:M]] --old URL1 --new URL2'
             where N and M default to HEAD.

The reason for this is so that I think there should be a diff command
with the same syntax as the merge command

   svn merge URL1[@N] URL2[@M] path

so that a user can preview the changes to be merged without having to
"translate" the command.

It is possible to have a directory called 'http:', and so have a
working copy path called 'http:/foo', which could be written with an
additional directory separator as 'http://foo', and two such paths
would cause an URL to URL comparison rather than an iterative BASE to
working copy comparison. I don't see this a serious problem, it's no
worse than 'svn mkdir', and 'svn diff --old . http://foo http://bar'
would recover the iterative behaviour.
