* Version 4.0.42.
+ * tests/install/create-leading: Use ../envvar-check rather than
+ open-coding the same tests.
+
+ * tests/envvar-check: Set/use $as_unset, for those shells
+ (like Ultrix4's /bin/sh) that don't accept `unset'.
+
+ * missing (--run): Use `eval' to run `"$@"'. Otherwise, Ultrix4.4's
+ /bin/sh fails and outputs garbage.
+
* doc/fileutils.texi (touch invocation): Mention the obsolescent usage.
* src/touch.c (usage): Tweak the obsolescent usage line so that
help2man recognizes it as such. Reported by Dan Jacobson.
