+************************************************
+WARNING: On this system, the built-in echo function of /bin/sh
+does not report failure when writing to a full device.
+To demonstrate, run this command:
+
+  /bin/sh -c 'echo hello > /dev/full; echo status=$?'
+
+Notice that the failing echo leaves its exit status set to zero
+and does not produce a diagnostic.
+
+That bug in /bin/sh would cause the tests of the nohup and groups
+scripts to fail, so those two are being removed from the list of
+programs checked by this test.
