Assuming I made this change myself in the past, although I don't remember!!
That would be my assumption, too. When I'm marking up Zen Cart (and plugin) files, I normally bracket my changes with //-bof and //-eof comments with the date.

That way, when I'm upgrading I know to review (and possibly carry over) the change.
