Note also that *other* non-graphical characters in Telnet data are also
displayed with C-style escape sequences, so any code that attempts to
parse that data must have code to handle those escape sequences
*regardless* of whether tabs are shown as tab characters or "\t", so:

	if the code to handle C-style escape sequences is present, one
	would merely have to add to that code the ability to handle
	"\t";

	if the code to handle C-style escape sequences is absent, one
	would have to add it anyway, at which point one might as well
	make it handle "\t" as well.
