null terminal?

[Tait <gnu...@t4...>]

As gnuplot allows more and more to be done within the program itself,
constructs like this are increasingly frequent:

> set term dumb
> min=10**10
> plot 'disy.100' u ($3<min?min=$3:min=min,$1):3
>
> set term x11
> plot 'disy.100' u 1:($3/min)

Should we perhaps create a null terminal (that silently discards
everything, like /dev/null) to facilitate iterating over files like
above? The additional output of using "set term dumb" can be inconvenient,
and there's no guarantee that any other particular terminal is present
on a given gnuplot installation.
