The tt(-E) flag, or the tt(BSD_ECHO) option, can be used to disable
these escape sequences. In the latter case, tt(-e) flag can be used to
enable them.
Note that for standards compliance a double dash does not terminate
option processing; instead, it is printed directly. However, a
single dash does terminate option processing, so the first dash,
possibly following options, is not printed, but everything following it
is printed as an argument. The single dash behaviour is different
from other shells. For a more portable way of printing text, see
tt(printf), and for a more controllable way of printing text within zsh,
see tt(print).
