[boost] Bug Fixing

Hey I am trying to get myself involved with the BOOST libraries and start contributing. I found a bug reported on trac, I fixed it and added the file as an attachment. I was curious to know that is this only the way to do it or I should send in patches using pull requests. I would be really glad if someone could guide me with the go abouts of contributing. Thanking you Cheers Shubhangee Verma
