Consider the following, as evaluated in *scratch*; (progn (require 'atomic-extents) (setq our-extent (make-extent 1 3)) ;; Make it such that point can never be within the extent. (set-extent-property our-extent 'atomic t) (goto-char 4) (delete-backward-char)) Now, I’d like that delete-backward-char to delete the whole extent; has anyone an idiom to do this, ideally avoiding wrapping or advising the various backward-delete-char-like functions? -- “I, for instance, am gung-ho about open source because my family is being held hostage in Rob Malda’s basement.
