(speedbar-update-current-file): Added call to

`speedbar-center-buffer-smartly' to improve the display.
(speedbar-center-buffer-smartly) Fixed off-by-one error in window
height calculation.
(speedbar-hack-buffer-menu): New function.
(speedbar-frame-parameters): Removed scroll bar width.
(speedbar-frame-mode): Change pointer shape for X
and W32 window-systems only.  When window-system is pc, bind the
speedbar frame name to "Speedbar", and select that frame so it is
displayed.
(speedbar-mode): Don't bind default-minibuffer-frame when
window-system is pc.
(speedbar-this-file-in-vc): Look for RCS/name as well as RCS/name,v.
(speedbar-directory-buttons-follow): Support both upper- and
lower-case drive letters.  Use directory-sep-char instead of a
literal backslash.
(speedbar-reconfigure-keymaps): Call
`easy-menu-remove' before reconfiguring for a new menu bar.
(speedbar-previous-menu): New Variable.
(speedbar-frame-plist): Remove pointers.
(speedbar-refresh): Prevent the mark from being deactivated.
(speedbar-buffer-kill-buffer): Refresh speedbar after killing a
buffer in the buffer display.
