R-alpha: R-0.50.a1: buglet in lsfit()

[Kurt Hornik]

I just discovered why
	abline(lsfit(x, y))
does not produce any output (as I mentioned on Friday).  In lsfit(), the
coefficients output component was incorrectly named "coef" and not
"coefficients", hence the coefficients method returned NULL ...

The patch below fixes the problem.
