+	- execute_null_command: if an empty simple command (no words, just
+	  redirections) requires a fork, reset top_level and exit if we
+	  longjmp there. This can happen with an expansion error while we
+	  evaluate the redirection.

+	- execute_connection: in default mode, bash performs jobs notifications
+	  in an interactive shell between commands separated by ';' or '\n'.
+	  It shouldn't do this in posix mode, since posix now specifies when
+	  notifications can take place
