karma-browserify coverage reports contain file include paths instead of source code
<p>Using karma-browserify to do unit tests with Jasmine. The tests correctly run but the coverage reports show file include paths instead of source code. You can reproduce this by installing the following project and run 'gulp unit':</p>

<p>Here is an example of the coverage report contents:</p>

<pre><code>typeof require === "function" &amp;&amp; require("/xxx/xxx/xxx/shackstack/app/media/script/service/utilities.js");
</code></pre>

<p>Here is my karma.config:</p>

<pre><code>module.exports = function(karma) {
    'use strict';
    karma.set({
        basePath: '',
        frameworks: [
            'jasmine',
            'browserify'
        ],
        files: [{
            pattern: 'app/media/script/service/*.js',
            included: true
        },
        {
            pattern: 'app/media/test/spec/*Spec.js',
            included: true

        }],
        reporters: [
            'progress',
            'coverage'
        ],
        preprocessors: {
            'app/media/script/service/*.js': [
                'browserify',
                'coverage'
            ],
            'app/media/test/spec/*Spec.js': [
                'browserify'
            ]
        },
        browsers: [
            //'Chrome',
            //'Firefox',
            //'Safari',
            'PhantomJS'
        ],
        singleRun: false,
        autoWatch: false,
        // browserify configuration
        browserify: {
            debug: true,
            transform: [
                'brfs',
                'browserify-shim'
            ]
        },
        coverageReporter: {
            type: 'html',
            dir: 'app/report/istanbul/',
            subdir: '.'
        },
        // If browser does not capture in given timeout [ms], kill it
        captureTimeout: 60000
    });
};
</code></pre>
