Allow control characters inside escape sequences

Taken from vt100 manual programmer:

	Control characters (codes \0 to \37 inclusive) are specifically
	excluded from the control sequence syntax, but may be embedded
	within a control sequence. Embedded control characters are executed
	as soon as they are encountered by the VT100. The processing of the
	control sequence then continues with the next character received.
