[Zope3-dev] possible bug in zc.relationship when passing empty container as target in isLinked

[Shaar Gabriel]

Hi
i think i found a bug in zc.relationship svn.
the bug is in shared.AbstractContainer.isLinked
if the target parameter is a container with no objects, then it resolves to 
False in a bool context and tokenization fails

target and tokenize({'target': target})

returns the target instead of the result of the tokenize function.
