Trying the nix CLI today, and I'm seriously impressed with the formatting of its --help output. Indented warnings, italics, bullets, even adding a left border to code snippets! It's a nice reminder to take full advantage of terminal features to help the reader.

Line-based diffs are easily muddled by wrapping/unwrapping with delimiters. If whitespace matters, you show the indented lines, and if whitespace doesn't matter, you don't know which } to match! Compare GitHub with difftastic here.

Yet another elisp gem on SO: https://stackoverflow.com/a/4459159/509706 Toggle hiding indented code -- great for getting an overview of big code files!
