Personal anecdote: I use "XXX" as a marker for "you must clean this up before committing/publishing", similar to "DO NOT PUBLISH" in a CMS. The reason I do this is because it visually stands out well when scanning through the output of `git add -p`. When used in that form it satisfies all the author's concerns, as it's just a marker to myself that presumably needs no other context (as I usually mark and resolve within a few hours).
