+From cd7091a7d88306004ca98c5dafcc40f44589b105 Mon Sep 17 00:00:00 2001

+Subject: [PATCH 1/3] src/dir.c: fix buffer-overflow warning
+
+Fix compiler warning:
+	src/dir.c:1294:7: warning: 'strncpy' specified bound depends on the
+			  length of the source argument [-Wstringop-overflow=]
+
+The existing code assumes `path` will never exceed `MAXPATHLEN`. Also the
+size of the buffer is increased by 1 to hold a path with the length of
+`MAXPATHLEN` and trailing `0`.
