What's with 3.21 src.tgz download?

[stevecoh1]

It lists itself as being 27923 KB on the site but when you're done downloading, you have 66MB. Looks like a tarred, but not zipped archive.

I experienced the same.
I think the browser decompresses this itself. You must admit that it really looks like cleartext ;-P
Perhaps a wrong mime-type or such ?!
