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...

It seems that newer packages use another readline library:

http://packages.ubuntu.com/lucid/gnuplot-x11
Package: gnuplot-x11 (4.2.6-1) [universe]

libedit2  (>= 2.5.cvs.20010821-1)
     BSD editline and history libraries
