logicals in data frames -- as.data.frame() should allow them

Currently, as.data.frame() , i.e., at least its "matrix" method,
still coerces logicals to factors.  I think this is not desired
and not according to the changes to read.table() for R 1.4.0
which allow logicals.

Does anybody see a reason against a change which would allow
logical matrices to become data.frames with logical variables ?
