More complete tmux support



Hi,

We've had this patch for a long time in OpenBSD ports, it's to complete tmux
support.

From 1d5a50cf32a496592ea0d6432a870d1f78b75f21 Mon Sep 17 00:00:00 2001

+# _tmux_aliasmap associative array above (if the comand in fact has an
+# alias). The rest should just work[tm].

+
+# tmux <http://tmux.sf.net> completion for zsh <http://zsh.sf.net>.
+#
+# Configuration:
+#
+# - On some OSs, the directory for tmux's server sockets may not be
+#   the default (which is /tmp/tmux-<uid>/), but say
+#   /var/run/tmux/tmux-<uid>, in which case the completion for
+#   'tmux -L <tab>' will not be able to find the sockets in the default
+#   location (debian does this, for instance); tell _tmux the right place
+#   to look:
+#       % zstyle ':completion:*:*:tmux:*:sockets' socketdir "/var/run/tmux/tmux-${UID}"
+#
+# - tmux knows a *lot* of sub-commands, hence 'tmux <tab>' returns a lot
+#   of possible completions. _tmux knows about all commands and their aliases.
+#   By default, both are offered. If you do not care about the aliases, do this:
+#       % zstyle ':completion:*:*:tmux:*:subcommands' mode 'commands'
+#
+#   The same can be done to only return aliases by setting the above style
+#   to 'aliases'. The default value is 'both' (but actually every value
+#   different from 'commands' and 'aliases' will have the same effect).
+#
+#   'lsw' is an alias for 'list-windows' for example; note that not all
+#   commands have aliases. So probably, either the default 'both' or
+#   'commands' makes most sense for this style.
+#
+# - For finer grained control over what is suggested as possible completions,
+#   the 'ignored-patterns' style may be used; suppose you think that only
+#   '*-window' or '*-windows' are worth being completed. You would get that
+#   behaviour like this:
+#       % zstyle ':completion:*:*:tmux:*:subcommands' ignored-patterns '^*-window(|s)'
+#
+#   Some tmux commands currently do not work if called from a shell prompt,
+#   so it would make sense to ignore them per default (at the time of writing,
+#   those commands are choose-{session,client,window}, confirm-before and
+#   find-window. This would ignore them:
+#       % zstyle ':completion:*:*:tmux:*:subcommands' ignored-patterns \
+#                'choose-*' 'confirm-before' 'find-window'
+#
+# The configuration for subcommand completions may be done in
+# this context: ':completion:*:*:tmux-<sub-command>:*:*'
+
+# Global variables; setup the first time _tmux is called.
+# For $_tmux_commands[] generation, see the very end of this file.
