Subject: [PATCH 05/11] solvergit: do not solve blobs twice
Date: Wed, 30 Jan 2019 04:44:24 +0000
Message-ID: <20190130044430.28189-6-e@80x24.org> (raw)
In-Reply-To: <20190130044430.28189-1-e@80x24.org>

In some cases, a file may ping-pong between blob IDs in the same
message when reverts occur.  So break out of this early.

This doesn't account for different abbreviations, but the
limited variations of abbreviations should alleviate the
problem.
