But perhaps it is a complex question because the implementation is
currently complex? Why not add a level of abstraction? We have on
one side the behaviour of escape and other keys in RISC OS and on
the other side a UnixLib program that has a separate signal mechanism
and file mechanism (e.g. stdin). I think that all we need is some
(possibly independent) code that does the matching between both
sides (a terminal like Nettle being an example of such code).
