zip empty directories

[Ben Anderson]

Hi,
I noticed that neither the zip or jar targets are including empty
directories.  I googled a little and found the was a regression issue way
back with 1.6 (.2 I think), but it was claimed to have been fixed.  I was
using 1.8.0 so I upgraded to 1.8.1, but am having the same issue.  Anyone
know of any workarounds besides adding dummy files to those directories?
Thanks,
Ben Anderson
