Now that we can have null bytes in Swift paths, we need a way for
operators to be able to locate such containers and objects. Our usual
trick of making sure the name is properly quoted for the shell won't
suffice; running something like
swift-get-nodes /etc/swift/container.ring.gz $'AUTH_test/\0versions\0container'
has the path get cut off after "AUTH_test/" because of how argv works.
So, add a new option, --quoted, to let operators indicate that they
already quoted the path.
Drive-bys:
* If account, container, or object are explicitly blank, treat them
as though they were not provided. This provides better errors when
account is explicitly blank, for example.
* If account, container, or object are not provided or explicitly
blank, skip printing them. This resolves abiguities about things
like objects whose name is actually "None".
* When displaying account, container, and object, quote them (since
they may contain newlines or other control characters).
