GitHub code show whitespace

A userscript that shows whitespace (space, tabs and carriage returns) in code blocks

• All spaces and tabs are shown.
• It works on repo file and diff-view pages, and gist pages.
• A toggle button is added to each file block and allows you to enable or disable the whitespace view.
• It does not interfere with the selection, copying & pasting of the code.
• A CSS tab-size of 2 is set by this script. This will be overridden by GitHub-Dark tab settings.
• This script is not fully compatible with the GitHub code folding userscript as they interfere with each other.
• Click this link to install from GitHub; or, install from GreasyFork or OpenUserJS.
