Instead of the leading '/', you could name the variable something that doesn't
end in _dir, _dirs, _file, _files, _path, _paths. I think no relativization is
done for variables that don't end in those paths.

pwd won't work on windows.

Done
Honestly nobody's tried developing Chrome for Android on windows. Mac used to
work and probably isn't far off. I don't want to spend time on windows right now
so I've moved the variable to an Android-only section.
