I think the problem is that the CLI client passes non-canonicalized
paths to the client library.

If we make the CLI client canonicalize its arguments using
svn_dirent_canonicalize(), the assertion does not trigger.
This makes sense since the 'svn add' command only accepts local working
copy paths, so it should try to interpret its arguments as such.

With the patch below I get an error such as:

$ svn add ^/
svn: warning: '/path/to/working/copy/file:/tmp/svn-sandbox/repos' not found

(The repository lives in "/tmp/svn-sandbox/repos".)

Do others agree? If so, I'd like to ask Uwe to send similar patches
for other subcommands, making sure they canonicalize their arguments

We should also consider changing the way "^/" is interpreted.
Maybe only commands that expect URLs as arguments should expand "^/"
to a URL? That way the above error would become:

$ svn add ^/
svn: warning: '/path/to/working/copy/^' not found

I'm running the diff below through make check now.
