** Many seldom-used generalized variables have been made obsolete.
Emacs has a number of rather obscure generalized variables defined,
that, for instance, allowed you to say things like:
(setf (point-min) 4)
These never caught on and have been made obsolete. The form above,
for instance, is the same as saying
(narrow-to-region 4 (point-max))
The following generalized variables have been made obsolete:
'buffer-local-value', 'visited-file-name', 'buffer-modified-p',
'buffer-name', 'buffer-string', 'buffer-substring', 'current-buffer',
'current-column', 'current-global-map', 'current-input-mode',
'current-local-map', 'current-window-configuration',
'default-file-modes', 'documentation-property', 'frame-height',
'frame-visible-p', 'global-key-binding', 'local-key-binding', 'mark',
'mark-marker', 'marker-position', 'mouse-position', 'point',
'point-marker', 'point-max', 'point-min', 'read-mouse-position',
'screen-height', 'screen-width', 'selected-window', 'selected-screen',
'selected-frame', 'standard-case-table', 'syntax-table',
'visited-file-modtime', 'window-height', 'window-width' and
'x-get-secondary-selection'.
