	Quite likely.  It's because the Enter key generates a character
code of 0x03.  Guess what.  ^C is also 0x03.  Red Ryder wants to generate
line feed (0x09) for the enter key, so it changes all character codes
of 0x03 to 0x09.  The two can be distinguished by looking in the modifiers
word to see if the control bit is on, but since the control bit didn't
exist when 9.4 was written...  VT100/VT52 emulation in Works probably
also started trying to do Enter to Linefeed mapping.
