Subject: [PATCH 1/2] config: Add 'config list' command
Date: Wed, 21 Mar 2012 09:31:37 +1100
Message-Id: <1332282698-7951-1-git-send-email-novalazy@gmail.com>
Precedence: list

Add a command to list all keys in a given configuration section.

One use is as follows: a MUA may prefer to store data in a central
notmuch configuration file so that the data is accessible across
different machines, e.g. an addressbook.  The list command helps
to implement features such as tab completion on the keys.
