If an application gives the first parameter to OSC 52, validate and pass
on to outside terminal. GitHub issue 3192.

When deleting or renaming a buffer and a buffer name is specified,
complain if the buffer doesn't exist instead of silently deleting or
renaming the most recent buffer. GitHub issue 3205.

Add args parsing callback for some future work, currently unused.

Hide struct args behind a couple of accessor functions.

Add a -w flag to set- and load-buffer to send to clipboard using OSC 52.
GitHub issue 2363.

Make struct cmd local to cmd.c and move it out of tmux.h.

Mass rename struct cmd_q to struct cmdq_item and related.

Add CMD_AFTERHOOK flag to the easy commands that don't need any special handling.

Add static in cmd-* and fix a few other nits.

I no longer use my SourceForge address so replace it.

Use member names in cmd_entry definitions so I stop getting confused
about the order.

Should add buffer if no -b.

Merge delete-buffer into cmd-set-buffer.c and change the paste buffer
API so it has one paste_free() rather than free_top and free_name
(everywhere that uses it already has the right pointer).

Move struct paste_buffer out of tmux.h.

Instead of setting up the default keys by building the key struct
directly with a helper function in the cmd_entry, include a table of
bind-key commands and pass them through the command parser and a

Instead of setting up the default keys by building the key struct
directly with a helper function in the cmd_entry, include a table of
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.

Add support for named buffers. If you don't name a buffer, things work
much as before - buffers are automatically named "buffer0000",
"buffer0001" and so on and ordered as a stack. Buffers can be named
explicitly when creating ("loadb -b foo" etc) or renamed ("setb -b
buffer0000 -n foo"). If buffers are named explicitly, they are not
deleted when buffer-limit is reached. Diff from J Raynor.

There is no longer a need for a paste_stack struct or for global_buffers
to be global. Move to paste.c.

Don't crash with a zero-length argument to setb, from J Raynor.

Add setb -a to append and a copy mode append command, from J Raynor with
minor changes.

Remove the barely-used and unnecessary command check() function.

Add a command queue to standardize and simplify commands that call other
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.

Make command exec functions return an enum rather than -1/0/1 values and
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
