I compiled gnuplot 5.0 from source. After this I have the same 
functionality in the terminal and in the gnuplot-console.

So it looks like the other effects comes from the "Debian gnuplot package"

The /usr/share/doc/gnuplot/README.Debian says:

"libreadline
-----------

Yes, the built in readline of gnuplot is bad. However, libreadline
cannot be used instead because it is licensed under the GPL, whereas
gnuplot has special licenses (patches only). Distribution of those
programs linked together is legally impossible but you may rebuild
your own custom package with readline. Please don't file bugs telling
me to use libreadline in gnuplot..."

Thank you for your help
