-    tests: fix false failure in nohup.sh in non tty builds
-    
-    * tests/misc/nohup.sh: When running tests without a controlling tty,
-    an exec failure is triggered in a subshell, which causes POSIX
-    shells to immediately exit the subshell.  This was brought
-    to notice by the newly conforming bash 4.3.
-    Fixes http:/bugs.gnu.org/16940
