Re: forwarded message from Stephen J. Turnbull

It turns out that VM is doing something tricky in the buffer and some things that _should_ be markers aren't. We should ask Ken'ichi what he thinks the correct behavior of `decode-coding-region' should be; I don't think it should move point, myself, but I don't know what the "correct" behavior should be if point starts strictly between START and END. One problem is in vm-mime.el (vm-mime-charset-decode-region), see my comments labeled ####: (defun vm-mime-charset-decode-region (charset start end) (or (markerp end) (setq end (vm-marker end))) (cond ((or vm-xemacs-mule-p vm-fsfemacs-mule-p) (if (or (and vm-xemacs-p (memq (device-type) '(x mswindows))) (and vm-fsfemacs-p (eq window-system 'x)) nil) (let ((buffer-read-only nil) (cell (cdr (vm-string-assoc charset vm-mime-mule-charset-to-coding-alist))) (oend (marker-position end)) ;; #### below, VM is jumping right into next week, ;; so make `opoint' a marker: ;; (opoint (point))) (opoint (vm-marker (point)))) (if cell (progn (set-marker end (+ start (or (decode-coding-region start end (car cell)) (- oend start)))) (put-text-property start end 'vm-string t) (put-text-property start end 'vm-charset charset) (put-text-property start end 'vm-coding (car cell)))) ;; In XEmacs 20.0 beta93 decode-coding-region moves point. ;; #### but opoint has moved due to edits! marker ;; version works (goto-char opoint)))) I'm not submitting this as a patch because it works only partially (I still get incorrect displays; now in the VM-summary buffer the _first_ encoded word is not getting decoded, although both are correct in the Presentation buffer). Sorry, I don't have time to investigate this more carefully and won't have time for a while. -- University of Tsukuba Tennodai 1-1-1 Tsukuba 305-8573 JAPAN Institute of Policy and Planning Sciences Tel/fax: +81 (298) 53-5091 __________________________________________________________________________ __________________________________________________________________________ What are those two straight lines for?
