CHANGES FROM 3.0 to X.X
* Change file reading and writing to go through the client if necessary. This
fixes commands like "tmux loadb /dev/fd/X". Also modify source-file to
support "-" for standard input, like load-buffer and save-buffer.
* Add ~/.config/tmux/tmux.conf to the default search path for configuration
files.
* Bump the escape sequence timeout to five seconds to allow for longer
legitimate sequences.
* Make a best effort to set xpixel and ypixel for each pane and add formats for
them.
* Add push-default to status-left and status-right in status-format[0].
* Add -F flag to send-keys to expand formats in search-backward and forward
copy mode commands and copy_cursor_word and copy_cursor_line formats for word
and line at cursor in copy mode. Use for default # and * binding with vi(1)
keys.
* Do not clear search marks on cursor movement with vi(1) keys.
* Add p format modifier for padding to width and allow multiple substitutions
in a single format.
* Add -f for full size to join-pane (like split-window).
* Handle OSC 7 (a VTE extension) and put the result in a new format (pane_path).
* Change new-session -A without a session name (that is, no -s option also) to
attach to the best existing session like attach-session rather than creating
a new one.
* Add an option to set the key sent by backspace for those whose system uses ^H
rather than ^?.
* Add formats for cursor and selection position in copy mode.
* Add support for percentage sizes for resize-pane ("-x 10%"). Also change
split-window and join-pane -l to accept similar percentages and no longer
document -p.
* Turn automatic-rename back on if the rename escape sequence is used with an
empty name.
* Make select-pane -P set window-active-style also to match previous behaviour.
* Do not use bright when emulating 256 colours on an 8 colour terminal because
it is also bold on some terminals.
