Hello,
plot2d plots the function as expected: nothing in interval [-1, 0].
draw2d plots the real part; make use of option draw_realpart=false to
avoid plotting in this interval. This option has been added recently and
is true by default; I've chosen this default for back compatibility, but
probably it'd be better to have the same behavior as in plot2d.
