Subject: [PATCH 3/6] xdiff: avoid signed vs. unsigned comparisons in xemit.c
Date: Tue, 11 Feb 2025 22:04:15 -0800	[thread overview]
Message-ID: <20250212060418.1645241-3-davvid@gmail.com> (raw)
In-Reply-To: <20250212060418.1645241-1-davvid@gmail.com>

The unsigned `ignored` variable causes expressions to promote to
unsigned. Use a signed value to make comparisons use the same types.
