Much thicker lines by default

[Dima K. <gn...@di...>]

Hi.

The default line width appears to have been affected in a recent commit:

 https://github.com/gnuplot/gnuplot/commit/b6c8dbfc63387be9e0c84d0d7b9ba6f480e5da8b

The commit notes don't say anything about it, so I'm wondering if this
change wasn't intentional. Is nobody else seeing this?
