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