Hhhmmm... This begs the historical question: When did LF replace CR/LF in UNIX?

Unix has always used NL as the terminator :-)

<CR><LF> was the line terminator in DEC operating systems that grew up around the same time as Unix. CP/M and MS-DOS inherited that from them since those systems were developed, in part, using cross compilers running on DEC gear with DEC OSes. Unix came from the Multics world where LF was used as the line terminator... Thankfully, neither CP/M nor MS-DOS picked up DEC's RMS...

The fun story on that Warner is after years of dogged defense of RMS, when C was written for VMS, Cutler had to add Stream I/O. The moment is was released, much (?most?) of customer base (including a lot of internal folks like the compiler runtime and DB folks) switched to using it. It was so much easier. I never heard Dave back down, but it I used to smile when I saw the statistics.
