CRLF as official line ending

[Chris Dee]

I also don't see why the file should be required to end in a newline.

IIRC, one of the original programs (LDraw or LEdit) ignored the last line if it was not terminated with <CR><LF>. That's why there was a convention (now obsolete) that the last line should be an empty comment. If the <CR><LF> was omitted from the comment it didn't matter.
