3 # Test a shell with error control. This only works in jobs mode; in compat
4 # mode, the default shell is always used, see InitShellNameAndPath.
5 #
6 # There is a subtle difference between error control and echo control.
7 # With error control, each simple command is checked, whereas with echo
8 # control, only the last command from each line is checked. A shell command
9 # line that behaves differently in these two modes is "false; true". In
10 # error control mode, this fails, while in echo control mode, it succeeds.
