Improve report of disk-usage on minified versions

This patch makes disk-usage report little bit more useful.
Here's visual example of `du` vs ``du -sh`:

    % du jade.js jade.min.js runtime.js runtime.min.js
    76      jade.js
    40      jade.min.js
    4       runtime.js
    4       runtimeruntime.min.js

    % du -bh jade.js jade.min.js runtime.js runtime.min.js
    74K     jade.js
    40K     jadejade.min.js
    3.6K    runtime.js
    1.8K    runtime.min.js
