Note that shtests simply does a 'grep -c err_exit' and substracts 1 to count the number of regression tests in a test script. Not all test scripts make temp dirs, so subtracting 2 instead won't do. src/cmd/ksh93/tests/*.sh: - Escape the err_exit call in the routine to create a temporary directory so that it is not counted as a regression test. That bypasses the alias, so we have to pass $LINENO manually.
