GitHub Actions seems to be hiding colored whitespace, and after lots of attempts I couldn't find a way to work it around. So instead I'm using a perl expression to replace trailing spaces with `·` and tabs with `<TAB>` in the ANSI colored diff output. This ensure that they're visible, and they are properly colored as expected too.
