SourceForge reorganization may affect gnuplot development site

[Ethan A M. <sf...@us...>]

SourceForge is "upgrading" (in other words replacing) its current project 
source code repositories, mailing lists, bug trackers, etc.

It is utterly unclear to me how much this will affect maintenance
or use of the gnuplot project pages, but I guess we will find out.

More information:
    https://sourceforge.net/p/upgrade/

If nothing else, apparently the URL to access the project pages
will change.
