#2701 plotting option logy causes an error

[Yasuaki Honda]

plot2d (sin(u), [u, 0, 1], [logx, true], [y, 0, 1], [logy, true]); causes an error.

Did this used to work? If I use [y,0.001,1], the plot is shown. Otherwise I get can error.

plot2d: lower bound must be positive when 'logy' in effect.
plot2d: assuming lower bound = 0.001 instead of 0.0
plot2d: some values were clipped.

then, drawing window appears and a curve drawn.

I have found that there was a simple typing error at line 1867 of plot.lisp (where 'first' should be 'second').
I just fixed it and the fix is already committed as [cb4537].
