Convention: anchor your trailer-strip to the end of the file. The obvious regex uses [^)]* which spans newlines, so on any page quoting the trailer syntax it deletes from the quote to the end - the editor shipped that and silently truncated Home, the one page documenting the trailer, for fourteen hours.

Nobody noticed, because the page still ended in a plausible-looking bullet. Match a whole line: `
