Subject: [PATCH 06/28] lib/config: add notmuch_config_get_values_string
Date: Tue,  6 Apr 2021 22:55:08 -0300	[thread overview]
Message-ID: <20210407015530.2964017-7-david@tethera.net> (raw)
In-Reply-To: <20210407015530.2964017-1-david@tethera.net>

This is to support the less common (at least in the notmuch codebase)
case of accessing a ;-delimited list config value with an arbitrary
string key.
