This commit was manufactured by cvs2svn to create tag 'TMUX_1_2'.

Permit keys in copy mode to be prefixed by a repeat count, entered with
[1-9] in vi mode, or M-[1-9] in emacs mode.

From Micah Cowan, tweaked a little by me.

+CHANGES FROM 1.1 TO 1.2, 10 March 2010
+
+* Switch to libevent.
+* Emulate the ri (reverse index) capability, ergo allowing tmux to at least
+  start on Sun consoles (TERM=sun, or sun-color).
+* Assign each entry a number, or lowercase letter in choose mode, and accept
+  that as a shortcut key.
+* Permit top-bit-set characters to be entered in the status line.
+* Mark no-prefix keys with (no prefix), rather than [] in list-keys.
+* New command show-messages (alias showmsgs), and new session option
+  message-limit, to show a per-client log of status lines messages up to the
+  number defined by message-limit.
+* Do not interpret #() for display-message to avoid leaking commands.
+* New window options window-status-format, and window-status-current-format to
+  control the format of each window in the status line.
+* Add a -p flag to display-message to print the output, instead of displaying
+  it in the status line.
+* Emulate il1, dl1, ich1 to run with vt100 feature set.
+* New command capture-pane (alias capturep) to copy the entire pane contents
+  to a paste buffer.
+* Avoid duplicating code by adding a -w flag to set-option, and show-options to
+  set, and show window options. The commands set-window-option, and
+  show-window-options are now aliases.
+* Panes can now be referred to as top, bottom, top-left, etc.
+* Add server-wide options, which can be set with set-option -s, and shown with
+  show-options -s.
+* New server option quiet (like -q from the command line).
+* New server option escape-time to set the timeout used to detect if escapes
+  are alone, part of a function key, or meta sequence.
+* New session options pane-active-border-bg, pane-active-border-fg,
+  pane-border-bg, and pane-border-fg to set pane colours.
+* Make split-window accept a pane target, instead of a window.
+* New command join-pane (alias joinp) to split, and move an existing pane into
+  the space (the opposite of break-pane), thus simplifying calls to
+  split-window, followed by move-window.
+* Permit S- prefix on keys for shift when the terminal/terminfo supports them.
+* Window targets (-t flag) can now refer to the last window (!), next (+), and
+  previous (-) window by number.
+* Mode keys to jump to the bottom/top of history, end of the next word, scroll
+  up/down, and reverse search in copy mode.
+* New session option display-panes-active-colour to display the active pane in
+  a different colour with the display-panes command.
+* Read the socket path from $TMUX if it's present, and -L, and -S are not
+  given.
+* Vi-style mode keys B, W, and E to navigate between words in copy mode.
+* Start in more mode when configuration file errors are detected.
+* Rectangle copy support added.
+* If attach-session was specified with the -r flag, make the client read-only.
+* Per-window alternate-screen option.
+* Make load-buffer work with FIFOs.
+* New window option word-separators to set the characters considered as word
+  separators in copy mode.
+* Permit keys in copy mode to be prefixed by a repeat count, entered with [1-9]
+  in vi mode, or M-[1-9] in emacs mode.
+* utf8 improvements.
+* As usual, additional code reduction, bug fixes, and manpage enhancements.
+
+CHANGES FROM 1.0 TO 1.1, 05 November 2009
+
+* New run-shell (alias run) command to run an external command without a
+  window, capture it's stdout, and send it to output mode.
+* Ability to define multiple prefix keys.
+* Internal locking mechanism removed. Instead, detach each client and run the
+  external command specified in the new session option lock-command (by default
+  lock -np), thus allowing the system password to be used.
+* set-password command, and -U command line flag removed per the above change.
+* Add support for -c command line flag to execute a shell command.
+* New lock-client (alias lockc), and lock-session (alias locks) commands to
+  lock a particular client, or all clients attached to a session.
+* Support C-n/C-p/C-v/M-v with emacs keys in choice mode.
+* Use : for goto line rather than g in vi mode. 
+* Try to guess which client to use when no target client was specified. Finds
+  the current session, and if only one client is present, use it. Otherwise,
+  return the most recently used client.
+* Make C-Down/C-Up in copy mode scroll the screen down/up one line without
+  moving the cursor.
+* Scroll mode superseded by copy mode.
+* New synchronize-panes window option to send all input to all other panes in
+  the same window.
+* New lock-server session option to lock, when off (on by default), each
+  session when it has been idle for the lock-after-time setting. When on, the
+  entire server locks when all sessions have been idle for their individual
+  lock-after-time setting.
+* Add support for grouped sessions which have independent name, options,
+  current window, but where the linked windows are synchronized (ie creating,
+  killing windows are mirrored between the sessions). A grouped session may be
+  created by passing -t to new-session.
+* New mouse-select-pane session option to select the current pane with the
+  mouse.
+* Queue, and run commands in the background for if-shell, status-left,
+  status-right, and #() by starting each once every status-interval. Adds the
+  capability to call some programs which would previously cause the server to
+  hang (eg sleep/tmux). It also avoids running commands excessively (ie if used
+  multiple times, it will be run only once).
+* When a window is zombified and automatic-rename is on, append [dead] to the
+  name.
+* Split list-panes (alias lsp) off from list-windows.
+* New pipe-pane (alias pipep) to redirect a pane output to an external command.
+* Support for automatic-renames for Solaris.
+* Permit attributes to be turned off in #[] by prefixing with no (eg nobright).
+* Add H/M/L in vi mode, and M-R/M-r in emacs to move the cursor to the top,
+  middle, and bottom of the screen.
+* -a option added to kill-pane to kill all except current pane.
+* The -d command line flag is now gone (can be replaced by terminal-overrides).
+  Just use op/AX to detect default colours.
+* input/tty/utf8 improvements.
+* xterm-keys rewrite.
+* Additional code reduction, and bug fixes.
