This adds two new options, window-size and default-size, and a new
command, resize-window.
The force-width and force-height options, and the session_width and
session_height formats have been removed.
The new window-size option tells tmux how to work out the size of
windows: largest means it picks the size of the largest session,
smallest the smallest session (similar to the old behaviour) and
manual means that it does not automatically resize
windows. aggressive-resize modifies the choice of session for largest
and smallest as it did before.
If a window is in a session attached to a client that is too small,
only part of the window is shown. tmux attempts to keep the cursor
visible, so the part of the window displayed is changed as the cursor
moves (with a small delay, to try and avoid excess redrawing when
applications redraw status lines or similar that are not currently
visible).
Drawing windows which are larger than the client is not as efficient
as those which fit, particularly when the cursor moves, so it is
recommended to avoid using this on slow machines or networks (set
window-size to smallest or manual).
The resize-window command can be used to resize a window manually. If
it is used, the window-size option is automatically set to manual for
the window (undo this with "setw -u window-size"). resize-window works
in a similar way to resize-pane (-U -D -L -R -x -y flags) but also has
-a and -A flags. -a sets the window to the size of the smallest client
(what it would be if window-size was smallest) and -A the largest.
For the same behaviour as force-width or force-height, use
resize-width -x or -y.
If the global window-size option is set to manual, the default-size
option is used for new windows. If -x or -y is used with new-session,
that sets the default-size option for the new session.
The maximum size of a window is 10000x10000. But expect applications
to complain and higher memory use if you make a window that big. The
minimum size is the size required for the current layout including
borders.
This change allows some code improvements, most notably that since
windows can now never be cropped, that code can be removed from the
layout code, and since panes can now never be outside the size of the
window, window_pane_visible can be removed.

command. This is used for the session, window and pane for all commands
in the command sequence if there is no -t or -s.
However, using it for all commands in the command sequence means that if
the active pane or current session is changed, subsequent commands still
use the previous state. So make commands which explicitly change the
current state (such as neww and selectp) update it themselves for later
commands. Commands which may invalidate the state (like killp) are
already OK because an invalid state will be ignored.
Also fill in the current state for all key bindings rather than just the
mouse, so that any omissions are easier to spot.
the state (client, session, winlink, pane) for it it before entering the
command. Each command provides some flags that tell the prepare step
what it is expecting.
This is a requirement for having hooks on commands (for example, if you
hook "select-window -t1:2", the hook command should to operate on window
1:2 not whatever it thinks is the current window), and should allow some
other target improvements.
The old cmd_find_* functions remain for the moment but that layer will
be dropped later.

keys. The default key bindings become the "prefix" table and -n the
"root" table. Keys may be bound in new tables with bind -T and
switch-client -T used to specify the table in which the next key should
be looked up. Based on a diff from Keith Amling.

bind-key commands and pass them through the command parser and a
temporary cmd_q.
As well as being smaller, this will allow default bindings to be command
sequences which will probably be needed soon.

commands and allow a command to block execution of subsequent
commands. This allows run-shell and if-shell to be synchronous which has
been much requested.
Each client has a default command queue and commands are consumed one at
a time from it. A command may suspend execution from the queue by
returning CMD_RETURN_WAIT and then resume it by calling cmd_continue() -
for example run-shell does this from the callback that is fired after
the job is freed.
When the command queue becomes empty, command clients are automatically
exited (unless attaching). A callback is also fired - this is used for
nested commands in, for example, if-shell which can block execution of
the client's cmdq until a new cmdq becomes empty.
Also merge all the old error/info/print functions together and lose the
old curclient/cmdclient distinction - a cmdq is bound to one client (or
none if in the configuration file), this is a command client if
c->session is NULL otherwise an attached client.
add a new value to mean "leave client running but don't attach" to fix
problems with using some commands in a command sequence. Most of the
work by Thomas Adam, problem reported by "jspenguin" on SF bug 3535531.
Originally, tmux commands were parsed in the client process into a
struct with the command data which was then serialised and sent to the
server to be executed. The parsing was later moved into the server (an
argv was sent from the client), but the parse step and intermediate
struct was kept.
This change removes that struct and the separate parse step. Argument
parsing and printing is now common to all commands (in arguments.c) with
each command left with just an optional check function (to validate the
arguments at parse time), the exec function and a function to set up any
key bindings (renamed from the old init function).
This is overall more simple and consistent.
There should be no changes to any commands behaviour or syntax although
as this touches every command please watch for any unexpected changes.
this screws up the choice of most-recently-used. Instead, break the time
update into a little function and do it when the session is attached.
Pointed out by joshe@.
- server option "exit-unattached" makes the server exit when no clients
are attached, even if sessions are present;
- session option "destroy-unattached" destroys a session once no clients
are attached to it.
These are useful for preventing tmux remaining in the background where
it is undesirable and when using tmux as a login shell to keep a limit
on new sessions.
