FWIW, it sounds like you both are saying it should work the same way.
The part that I suspect Julian was missing was that before you made
this change many of the subcommands were essentially adding what was
in the changelist to what was in CWD which really does not make any
sense. And clearly I think a user expects:

svn info --changelist foo /path

To show the info for the items in /path that belong to changelist foo.
 That is what Julian says it should do and that is what Mike just made
it do with these changes.
