title: How to prevent git commit if specific phrase in changes is detected?
body: <p>I noticed some patterns, that developers tend to do - like committing javascript tests with <code>fdescribe</code> or <code>fit</code> left in them (which means only one test/suite will be running), usually that is found in review phase, but it would be nice to catch those small things earlier. Wondering if there is a way to configure git to prevent commit if some pattern is detected within the changes? </p>
