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.
