No, I really do have them all in my working copy. I use branches and
tags *reeeeallly* heavily in some projects, so I'll often check out my
working directory from the repository root.

This does work, why doesn't this work giving working copies instead?
Take this tiny example:
$ svn info
Node Kind: directory
$ ls branch
$ svn diff --old=file:///tmp/repos/branch/tag1
$ svn diff --old=branch/tag1 --new=branch/tag2
svn: Incorrect parameters given
svn: Sorry, svn_client_diff was called in a way that is not yet
svn: do_diff: paths aren't equal!
(that doesn't work!)
It seems like it should, because of the following from 'svn diff
diff (di): display the differences between two paths.
usage: 1. diff [-r N[:M]] [--old OLD-TGT] [--new NEW-TGT] [PATH ...]
2. diff -r N:M URL
3. diff [-r N[:M]] URL1[@N] URL2[@M]
1. Display the differences between OLD-TGT and NEW-TGT. PATHs, if
given, are relative to OLD-TGT and NEW-TGT and restrict the output
to differences for those paths. ***OLD-TGT and NEW-TGT may be
working copy paths or URL[@REV].*** (emphasis mine)
OLD-TGT defaults to the path '.' and NEW-TGT defaults to OLD-TGT.
N defaults to "BASE" or, if OLD-TGT is an URL, to "HEAD".
M defaults to the current working version or, if NEW-TGT is an URL,
'-r N' sets the revision of OLD-TGT to N, '-r N:M' also sets the
revision of NEW-TGT to M.
In #1, this seems to say pretty clearly that it can be a URL or a
working version. Maybe this is a bug or a "wishlist" kind of feature,
but it seems like the documentation supports this format.
Anyway, thanks for the message. I can at least do what I need to with
the longer URI format, but it seems like it should work this other way
as well, since I have all the branches checked out.
