command when the shell exits but it does not work in ksh when the shells exits "implicitly" (without an explicit exit/return statement). These new tests cover both sh and ksh. The ksh part of this does not strictly belong to this directory, but I think it'd be nice to extend all the tests in here to cover both interpreters whenever that makes sense, much like we do with the file system tests.
