pkgs contain non URL safe characters

Some packages contain "+" symbol which is a way of encoding spaces in a 
URL. This means that I'm having trouble hosting our pkg repository 
behind cloudfront/S3.

I wasn't sure where to post this issue, so I put more details here:

Is there a workaround for this issue? Could pkg-fetch escape such 
characters when interacting with a http repository?
