CR & LF come to us from the Good Old Days of teletypes. CR returned the
mechanism so the next character would print in the 1st column; LF advanced the
paper a line. The 2 were separate so that a CR by itself could be used to
overprint a line.

In my early computing experience we didn't deal with ASCII, much less with
non-graphic control characters. (I'm not even sure if the CDC-6400's 6-bit
character set had those.) Input was either on 80-column punched cards, or in
record-oriented disk files that mimicked punched cards. Output went to 600-LPM
line printers, with paper motion controlled by the 1st character of each line
(space to advance to the next line, '+' to overprint the current line, and '1'
for a form feed).
