	Terminals have to do more with job control and basic (kernel’s)
	line editing functions, rather than ECMA-48 (AKA “ANSI”)
	processing or, say, pseudographics support.  (Be sure to check
	the POSIX definition of the terminal device interface [1].)

	Frankly, I don’t want to insist on this bug being fixed.

	However, I believe it should be left open (even if wontfix), at
	least so that the workaround below remains visible to the users.

	TIA.
