From 7d0c27e57c5433127a6b066490225462a0ca43ef Mon Sep 17 00:00:00 2001
From: Nicholas Marriott <nicm@cvs.openbsd.org>

Subject: Add initial framework for more powerful formatting of command output
 and use it for list-{panes,windows,sessions}. This allows more descriptive
 replacements (such as #{session_name}) and conditionals.

Later this will be used for status_replace and list-keys and other
places.
