What’s the trick to get the background color to extend across the entire line?
In Emacs 27, add an `:extend t` property to the face. In Emacs 26 and earlier, IIRC, you need to make sure that the newline at the end of the line is also fontified. (That may actually be necessary in Emacs 27 as well, in addition to the `:extend` property...)
