Not yet but if you tolerate these hostile entries then it means that all 
access with relative paths containing a "." or ".." element will be 
ambiguous. It will break relativize, normalize, and maybe other path 
operations. I assume it will break copy/move operations when the source 
is in a zip file and the target is in a non-zip file. I suspect it would 
also need to encode file names when open zip file for read/write access 
because the native file system is used for caching.
