!ターミナルの色設定
どうも見辛いので，少しずつ設定する．
 M-x list-faces-display
で，見辛い色をみつけて，
 (set-face-foreground 'minibuffer-prompt "brightblue")
 (set-face-foreground 'font-lock-function-name-face "brightblue")
 (set-face-foreground 'dired-directory "brightblue")
 (set-face-foreground 'info-header-xref "brightblue")
 (set-face-underline  'info-header-xref t)
 (set-face-foreground 'info-xref "brightblue")
 (set-face-underline  'info-xref t)
 (set-face-foreground 'button "brightblue")
 (set-face-underline  'button t)
とかする．
