My forking a repository workflow is as below.

$ git clone --origin upstream git@github.com:atom/atom.git .
$ hub fork # set the remote name to $MYNAME
$ git remote rename $MYNAME origin
$ git remote -v
origin  git@github.com:$MYNAME/atom.git (fetch)
origin  git@github.com:$MYNAME/atom.git (push)
upstream        git@github.com:atom/atom.git (fetch)
upstream        git@github.com:atom/atom.git (push)
$ git checkout -b my-awesome-feature

In this case, open-on-github opens my fork page, but I always expect to open original project's page(upstream/master). I use the git config in order to solve this problem.

$ git config atom.open-on-github.remote upstream

This patch will also fix #48
