I don't understand the question: the user of delete/delq/nconc (the one
reading their docstring or their texinfo doc) is the person
reading/writing the code, and the optimization is the act of choosing
delete over remove or delq over remq or nconc over append, which is
exactly what the reader will want to know, I think.
