Re: flushing out buffer of output PS file, OLDPS vs PS

The delete(wks) necessity was added in 6.1.2.

http://ncl.ucar.edu/prev_releases.shtml#6.1.2

Such action was always recommended, but not required up until this
6.1.1/6.1.2 version. Beyond that, I assume the developers could give you
more info on the change. Because of this change, the "oldps" type was left
to allow for backwards compatibility.
