recenter the visited source file. Its value can be a number (for example,
0 for top line, -1 for bottom line), or nil for no recentering.
+** The mode-line display a `@' if the default-directory for the current buffer
+is on a remote machine, or a hyphen otherwise.
+** The new command balance-window-area balances windows both vertically
+and horizontally.

* Startup Changes in Emacs 23.1
** New command kill-matching-buffers kills buffers whose name matches a regexp.
+** Minibuffer changes:
+
+*** isearch started in the minibuffer searches in the minibuffer history.
+Reverse isearch commands (C-r, C-M-r) search in previous minibuffer
+history elements, and forward isearch commands (C-s, C-M-s) search in
+next history elements. When the reverse search reaches the first history
+element, it wraps to the last history element, and the forward search
+wraps to the first history element. When the search is terminated, the
+history element containing the search string becomes the current.

* New Modes and Packages in Emacs 23.1
*** VC has some support for Mercurial (hg).
+*** VC has some support for Git.
+
** sgml-electric-tag-pair-mode lets you simultaneously edit matched tag pairs.
** BibTeX mode:
If `default-directory' is a remote file name, subprocesses are started
on the corresponding remote system.
+** C-x C-q in dired-mode now runs the command wdired-change-to-wdired-mode.

** In `condition-case', a handler can specify "let the debugger run first".
You do this by writing `debug' in the list of conditions to be handled,
+++
** The new function `start-file-process is similar to `start-process',
but obeys file handlers. The file handler is chosen based on
-`default-directory'.
+`default-directory'. The functions `start-file-process-shell-command'
+and `process-file-shell-command' are also new; they call internally
+`start-file-process and `process-file', respectively.

-** `file-remote-p' has a new optional parameter CONNECTED.
-With this paramter passed non-nil, it is checked whether a remote
-connection has been established already.
+** `file-remote-p' has new optional parameters IDENTIFICATION and CONNECTED.
+IDENTIFICATION specifies which part of the remote identifier has to be
+returned. With CONNECTED passed non-nil, it is checked whether a
+remote connection has been established already.
** The two new functions `looking-at-p' and `string-match-p' can do
the same matching as `looking-at' and `string-match' without changing
the match data.
+
+** The interactive-form of a function can be added post-facto via the
+`interactive-form' symbol property. Mostly useful to add complex interactive
+forms to subroutines.
