Google Java Format Pre-Commit Hook

My team decided to standardize on the Google Java Style Guide for formatting Java code; and not finding a drop-in git pre-commit hook for the Google Java Format library, I whipped one up and pushed it to GitHub as the Google Java Format Pre-Commit Hook project.

To use it, clone the repo, and link its pre-commit.sh script as the .git/hooks/pre-commit script in whatever project you want to use it with (or call it from your existing .git/hooks/pre-commit script, if you already have one). The script automatically downloads the Google Java Format library, and runs it over all staged .java files whenever you make a commit (and fails the commit if there are any formatting issues it can't automatically clean up).

You can skip the hook by including the --no-verify flag on an individual commit, or by setting the NO_VERIFY environment variable in your shell to be not empty prior to running a sequence of commits (like a merge or rebase). Full details for install and usage are in the project README.
