[webkit-dev] Directory upload experimental feature

[David Kilzer]

Also, I was simply pointing out existing behavior, not arguing for/against the zip file format.

I think this is only true for Mac OS X style bundles, not all folders.

Having written some code I think I have something that works pretty well, and I'd like to land it on an experimental basis in WebKit, but want to reach out early before trying to put any code in the tree.  The plan that comes to mind is a new ENABLE_DIRECTORY_UPLOAD flag, but I'm completely open to other options.
