Either the builtin readline supports HOME, END and DELETE, so this is a real bug in Ubuntu. Or either it doesn't and this is invalid since nobody can legally distribute binaries of gnuplot + gnu-readline. It is really sad that gnuplot developers do not wish to solve this issue: either change the license of gnuplot or drop support for gnu-readline so the builtin readline gets more attention).
