doc: update curl usage in COLLABORATOR_GUIDE

[silverwind]

Looks like Github now redirects the patch urls from

https://github.com/iojs/io.js/pull/1382.patch

to

https://patch-diff.githubusercontent.com/raw/iojs/io.js/pull/1382.patch

so curl now needs to follow that redirect.

LGTM but maybe add one or two lines to the commit log explaining the change. The idea is that when looking at the history, you don't have to look at the diff to figure out what the actual change was.

Thanks, will do.

btw there is apply-pr utility I wrote that has been pretty handy: https://github.com/petkaantonov/apply-pr

Applying pr is like: apply-pr --remote=upstream 1234 where 1234 is the pr id :)

Another option is to add fetch = +refs/pull/*/head:refs/pr/* to your .git/config and then you can merge PRs with git merge refs/pr/1234 (or cherry-pick or whatever you prefer.)

Noted, but that is kinda annoying.

cc @iojs/collaborators to notify the rest of the change.

Another alternative is to make curl follow redirects by default:

echo '-L' >> ~/.curlrc
