The name Ghostel sounds like a tribute to the Ghost of John Postel, whose law is a good thing for a terminal emulator to respect:

https://en.wikipedia.org/wiki/Robustness_principle

>In computing, the robustness principle is a design guideline for software that states: "be conservative in what you do, be liberal in what you accept from others". It is often reworded as: "be conservative in what you send, be liberal in what you accept". The principle is also known as Postel's law, after Jon Postel, who used the wording in an early specification of TCP.[1]

>In other words, programs that send messages to other machines (or to other programs on the same machine) should conform completely to the specifications, but programs that receive messages should accept non-conformant input as long as the meaning is clear.
