Yes it's fine, the square brackets are better.

I really like gnuplot and the gnuplot module. It is great to be able
to include the data inline with the document. And it would be nice to
see it part of the distribution. I am using a stock debian gnuplot, so
I don't know the implications of the context and TikZ terminals. Does
it mean I would not end up with so many  *-gnuplot-* files? :)
