github howto reconfigure git repository if cloned original and forked later
# so let's say you cloned repo someone/project like this
git clone git://github.com/someone/project.git
# you use it and then later on discover a bug.
# to fix it you create a fork on github to which you can
# write and issue a pull request, but now your origin is
# someone/project instead of you/project .
# fix it like this:
git remote rename origin upstream
