Gnuplot 5.4.7 release tarball available for testing

[Ethan A M. <me...@uw...>]

I have placed a pre-release tarball of 5.4.7 on the testing area of SourceForge

    https://sourceforge.net/projects/gnuplot/files/gnuplot/testing/gnuplot-5.4.7testing.tar.gz

The number of bug fixes is surprisingly large, given how late this is in the
5.4 series. Many of these bugs date back to earlier versions of gnuplot but
either were not reported or not considered fixable until recently.
I had been thinking that this would be the last patchlevel release for 5.4
but now I am not so sure. 

If no problems are reported, I plan to use this for release of 5.4.7
next week.
