Another good thing from this series is there are fewer --no-options to complete.

About the annotating unused parameters related to segfault bug fixes
in this series. Should we just add something like

 if (unset)
    BUG("This code does not support --no-stuff");

which could be done in the same patches that fix the segfault, and it
extends the diff context a bit to see what these callbacks do without
opening up the editor, and also serves as a kind of annotation?
