Subject: [PATCH 14/37] solver: more verbose blob resolution
Date: Mon, 21 Jan 2019 20:52:30 +0000	[thread overview]
Message-ID: <20190121205253.10455-15-e@80x24.org> (raw)
In-Reply-To: <20190121205253.10455-1-e@80x24.org>

Help users find out where each step of the resolution came from.
Also, we must clean abort the process if we have missing blobs.

And refine the output to avoid unnecessary braces, too.
