Actually, I think that without the --new and --old that is just diffing
both tags2 individually against the latest revision (i.e. show me the
local mods in both branches).

Although, I do admit that the first thing I tried was that syntax,
before I realized what it was doing.

Well, it seems like it should work with the --new/--old syntax with
working directories like I mentioned before, so maybe that is an issue,
but I think the "svn diff branch/tag1 branch/tag2" behavior actually
does kind of make sense (otherwise, you couldn't do "svn diff *.txt" or
something)
