From 83d44c01a9494fdd1935012f3bad5ed805c750a3 Mon Sep 17 00:00:00 2001
From: Per Cederqvist <ceder@lysator.liu.se>

Subject: [PATCH] Implement "tg summary --deps" as a shell function.
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

This avoids running "$tg summary --deps" from all commands that need
that information internally.
