the state (client, session, winlink, pane) for it it before entering the

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.

While here, also tidy up a few bits of options and hooks handling (use

poor idea that was fairly quickly replaced by SGR mouse input (which is
now widespread). It is impossible to tell the difference between UTF-8
and non-UTF-8 mouse input; since the mouse-utf8 option was removed tmux
has not handled it correctly in any case; and it is ridiculous to have
three different forms of mouse input.
of storing a full grid_cell with UTF-8 data and everything, store a new
type grid_cell_entry. This can either be the cell itself (for ASCII
cells), or an offset into an extended array (per line) for UTF-8
data.
This avoid a large (8 byte) overhead on non-UTF-8 cells (by far the
majority for most users) without the complexity of the shadow array we
had before. Grid memory without any UTF-8 is about half.
The disadvantage that cells can no longer be modified in place and need
to be copied out of the grid and back but it turned out to be lot less
complicated than I expected.
uint64_t and converting UTF-8 to Unicode on input and the reverse on
output. (This allows key bindings, there are still omissions - the
largest being that the various prompts do not accept UTF-8.)
around, we can't use file descriptors for the working directory because
we will be unable to pass it to a privileged process to tell it where to
read or write files or spawn children. So move tmux back to using
strings for the current working directory. We try to check it exists
with access() when it is set but ultimately fall back to ~ if it fails
at time of use (or / if that fails too).
#{=10:...} length limit, add #{t:...} to convert a time_t format to a
string, #{b:...} for basename and #{d:...} for dirname. Remove all the
foo_string time formats as they can now be replaced by "t:", for example
#{window_activity_string} becomes #{t:window_activity}.
the main loop after events that may have changed the pane, but do so at
most once every 500 millis. If the pane changed too soon, use a timer to
ensure that a check happens later.
can't do the name check every loop, because that is too expensive, and
we can't make sure it only happens infrequently because we have no idea
when the next change will happen.
but that can only happen when we have already been woken up by a read
event, so there is no need for a timer, we can just check the changed
flag on the end of that read event (we already loop over the windows to
check for bells etc anyway).
socketpair and setting it to -1 to mark when the other side is

server at a time; it may be toggled or cleared with select-pane -m and
-M (the border is highlighted). A new target '~' or '{marked}' specifies
the marked pane to commands and it is the default target for the

mark the source pane and then change to the target pane to run swapp or
joinp).

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.
options for "mouse-this" and "mouse-that", mouse events may be bound as
keys and there is one option "mouse" that turns on mouse support
entirely (set -g mouse on).
See the new MOUSE SUPPORT section of the man page for description of the
key names and new flags (-t= to specify the pane or window under mouse
as a target, and send-keys -M to pass through a mouse event).
The default builtin bindings for the mouse are:
bind -n MouseDown1Pane select-pane -t=; send-keys -M
bind -n MouseDown1Status select-window -t=
bind -n MouseDrag1Pane copy-mode -M
bind -n MouseDrag1Border resize-pane -M
To get the effect of turning mode-mouse off, do:
unbind -n MouseDrag1Pane
unbind -temacs-copy MouseDrag1Pane

irritating flaws:
a) The old way of always using the top or left if the choice is
ambiguous is annoying when the layout is unbalanced.
b) The new way of remembering the last used pane is annoying if the
layout is balanced and the leftmost is obvious to the user (because
clearly if we go right from the top-left in a tiled set of four we want
to end up in top-right, even if we were last using the bottom-right).
So instead, use a combination of both: if there is only one possible
pane alongside the current pane, move to it, otherwise choose the most
recently used of the choice.

The -a flag to set can be used to add to rather than replace a style. So:

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.
or unzoom (restored to the normal layout) if it already zoomed, bound to C-b z

We considered making this a new layout but the requirements are quite different
from layouts so decided it is better as a special case. Each current layout
cell is saved, a temporary one-cell layout generated and all except the active
pane set to NULL.

Add a simple form of output rate limiting by counting the number of
certain C0 sequences (linefeeds, backspaces, carriage returns) and if it
exceeds a threshold (current default 50/millisecond), start to redraw
the pane every 100 milliseconds instead of making each change as it
comes. Two configuration options - c0-change-trigger and
c0-change-interval.
This makes tmux much more responsive under very fast output (for example
yes(1) or accidentally cat'ing a large file) but may not be perfect on
all terminals and connections - feedback very welcome, particularly
where this change has a negative rather than positive effect (making it
off by default is a possibility).

Simplify the way jobs work and drop the persist type, so all jobs are
fire-and-forget.
Status jobs now managed with two trees of output (new and old), rather
than storing the output in the jobs themselves. When the status line is
processed any jobs which don't appear in the new tree are started and
the output from the old tree displayed. When a job finishes it updates
the new tree with its output and that is used for any subsequent
redraws. When the status interval expires, the new tree is moved to the
old so that all jobs are run again.
This fixes the "#(echo %H:%M:%S)" problem which would lead to thousands
of identical persistent jobs and high memory use (this can still be
achieved by adding "sleep 30" but that is much less likely to happen by
accident).
