Please install the following script as <code>.git/hooks/pre-commit</code> (don't forget to do <code>chmod +x</code> on it) that will perform several checks on changes before they are committed:

<source lang="bash">
#!/bin/bash
#
# Hook script to verify what is about to be committed.
# Called by "git commit" with no arguments. The hook should
# exit with non-zero status after issuing an appropriate message if
# it wants to stop the commit.

# This hook:
# * checks for whitespace errors
# * checks for bad characters
# * runs tests on changes that are about to be committed (other modifications
# except for untracked files are stashed for this)
