recenter-top-bottom synced from GNU and new default for C-l
Partial implementation of recenter-top-bottom. GNU has support for
scroll-margin that is not in XEmacs so that is left out.
lisp/ChangeLog:
2012-09-18 Mats Lidell <matsl@xemacs.org>
* window-xemacs.el (recenter-positions): New defcustom.
(recenter-top-bottom): New command.
(recenter-last-op): New defvar.
* replace.el (perform-replace): Let-bind recenter-last-op to nil.
For def=recenter, replace `recenter' with `recenter-top-bottom'
that is called with `this-command' and `last-command' let-bound to
`recenter-top-bottom'. When the last `def' was not `recenter',
set `recenter-last-op' to nil.
* keydefs.el (global-map): Make recenter-top-bottom new default
for C-l.

| 1481 This command, which is the default binding for @kbd{C-l}, acts like | |
| 1482 @code{recenter}, except if called with no argument. In that case, | |
| 1483 successive calls place point according to the cycling order defined | |

| 1488 This variable controls how @code{recenter-top-bottom} behaves when | |
| 1489 called with no argument. The default value is @code{(middle top | |
| 1490 bottom)}, which means that successive calls of | |
| 1491 @code{recenter-top-bottom} with no argument cycle between placing | |
| 1492 point at the middle, top, and bottom of the window. | |
