in thread Remove an existing, non-empty, directory re: Archive::Zip

I processed another Zip file last night and found that this technique sometimes (maybe) leaves behind null entries. That is, one directory member with no files and then the same directory with each file following. Unfortunately, I don't have the time to track down what's going on. Since I had to do some manual changes to the Zip file, that may have caused the phenomenon.

I can ignore those null entries and so that's my solution.

Note: One source of confusion in using Archive::Zip is that, I think there is no clear distinction in the POD between directories outside the Zip and directories inside the Zip file. If that distinction were more clearly presented, it may be easier to use. Just a thought.
