(After this change, r29672:
$ svn cl blabla
svn: Try 'svn help' for more info
svn: Not enough arguments provided

Yes we do want to require an explicit target. I can't see the use case of "Add
the current directory to this changelist" to be anywhere near common enough to
warrant it being the default action of the "changelist" command.
Some of our commands default to acting on the current directory because it's
very commonly wanted and a "safe" default (like "svn status"). There's no need
for other commands to take the same or any default where it's not very commonly
useful and safe to do so.
Consider "svn cl --recursive blabla DIR" which currently means add all files
under DIR. Is it sensible to have a default target of "." in this case? Imagine
if changelists do eventually support directories. Maybe the default action on a
specified directory will be to add it as depth==0, or maybe as depth==infinite.
Is it sensible to have a default target of "." in any of these cases?
Save the default syntax for some (as yet unknown) purpose that really warrants
it. For example, maybe we will eventually have a way to "view" or "activate"
(in some sense) a changelist, and maybe one of those actions will become very
common. Then it might make sense to make "svn cl blabla" mean that common action.

No, we don't. The exception "Not enough arguments provided" has nothing to do
with whether directories are supported.
I hope that makes sense to you now.
