If you change the name of your repo, or move it to a different organization, GitHub still allows that URL to work which is nice if you have projects referencing the old repo location. But component fails in this case because it doesn't seem to handle the 301 redirect.

What do you think about adding support for 301 redirects, so this error doesn't occur?

  error : failed to fetch https://raw.github.com/user/repo/master/index.js, got 301 "Moved Permanently"

The reason is, even if I were to update all my projects referencing the old repo location so they pointed to the new location, if anyone was going to try to install/build in the middle of that process, it would fail.

By adding support for 301 redirects, you could be more relaxed about it.

Thoughts?
