block a range of versions via '<=' and '>='

[GeJ]

This is more a wishlist than an issue.

I was thinking about blocking a range of versions for a dependency module that are known to be problematic. I tried a combination of '<=4.04,>=4.09' and got the following error :

illegal requirements: minimum exceeds maximum

The thing is I don't necessarily need the users to upload to 4.09 when I know that the 3.xx branch just works. Right now, I'm blocking the 4 versions that cause a problem one by one, but it'd be nice if could block a range as well.
