bug#7982: highlighted charactor still remains after moving cursol

[takuma maruyama]

highlighted charactor with "(show-parent-style '_expression_)" still remains after moving cursol.

i wrote following .emacs setting:

;----------------------------------------------------

; displaysize

(setq initial-frame-alist

     (append '((top . 40)

(left . 45)

(width . 40)

(height . 35)) initial-frame-alist))

; parent highlight

(show-paren-mode t)

(setq show-paren-style '_expression_)

(set-face-background 'show-paren-match-face "PaleTurquoise")

(set-face-foreground 'show-paren-match-face "SteelBlue")

(set-face-underline-p 'show-paren-match-face t)

; remove startup message

(setq inhibit-startup-message t)

;----------------------------------------------------

and restarted emacs.

like "$emacs ~/.emacs".

when i move the cursol to the end of long line such as

'(set-face-background 'show-paren-match-face "PaleTurquoise")',

then the end of highlight charactor still remain after moving cursol to the other line.

emacs shows the line such as '(set-face-background 'show-paren-match-face "PaleTurquoise")Pa'.

'Pa' is highlighted charactor after moving cursol.

is it bug? or my .emacs setting is bad?

---my enviroment---

GNU Emacs 23.1.1 (i used apt-get command to get emacs)

ubuntu 10.10
