+find: fix regression in status processing for path arguments
+
+Regression added in commit 14158b4127dba30466c50147b868a6a89702960b
+"find: add optional support for '-exec ... {} +'"
+
+This commit causes find to exit on the first path argument that was not
+found, which breaks existing scripts and is incompatible to other
+implementations.
+
+Instead of exiting on the first failure, return EXIT_FAILURE at the end
+if any error occurred.
