No, I think. Reverse call tree shows

       17747  68% - delete-char
       14911  57%  + widget-default-create
        1864   7%  + widget-checklist-add-item
         972   3%  + widget-editable-list-entry-create
        3320  12% + widget-default-create

which likely corresponds to ";; Parse % escapes in format." code,
present in `widget-default-create', `widget-checklist-add-item', and
`widget-editable-list-entry-create'.
