Quick merge of upstream pull request

pr.sh

git clone (my fork url here)
cd (repo name here)
git remote add (upstream url here)
pr() { git fetch upstream pull/$1/head:pr$1 && git merge --commit pr$1; }

# now you're set.  Pick your PRs, say 1, 2, and 55:

pr 1 # fetch, merge, and autocommit upstream's Pull Request #1
pr 2 # same for PR #2
pr 55 # etc.
# ...

# Assuming you had no merge conflicts (or sorted them out) and have rebased if you wanted to squash:

git push # push the changes to your fork
