Source for a bookmarklet I run before bothering to read JavaScript on GitHub (or anywhere else, for that matter). Replaces 2-space tabstops with tabs rendered at 4 columns (my preferred tabstop width, but the size can be customised to be 6, 8 or 3 if you prefer.
Seriously, this is how much I hate this shit. Expect to find this available as a Chrome extension someday, once I get sick of routinely pressing this bookmarklet each time I visit GitHub-hosted source code.
Expect this list to grow over time.
