swift client psudeo-folder syntax is applied inconsistently

[clayg]

We allow pseudo-folder syntax for uploads:

vagrant@saio:~$ swift upload test/folder deleteme
deleteme

^ results in an object named "folder/deleteme" created in the container test.

We do not allow pseudo-folder syntax for delete or stat, but do provide a helpful explanation:

vagrant@saio:~$ swift delete test/folder deleteme
WARNING: / in container name; you might have meant 'test folder' instead of 'test/folder'.

vagrant@saio:~$ swift stat test/folder deleteme
WARNING: / in container name; you might have meant 'test folder' instead of 'test/folder'.

One place where the pseudo-folder syntax would be extremely useful is in listings, but here no useful explanation is provided:

vagrant@saio:~$ swift list test
folder/deleteme
vagrant@saio:~$ swift list test/folder
Usage: swift list [--long] [--lh] [--totals] [--prefix <prefix>]
