This is incorrect. #\Newline has no relation with CR or LF.

At least on sbcl there seems to be a relation:
Implementation specific.

Okay, possible.
But I can say that at least sbcl works this way.
And clisp. Not to forget Allegro. Oh, and cmucl.
But maybe all the other lisps act different in that regard, so probably
you are right, and there mostly is no relation between #\Linefeed and a
#\Newline. ;)

All running Unix right?
That is because #\Linefeed is a gives a newline under Unix.
However under Windows it just goes to the next line.
A #\Return is needed to send it to the beginning of line.
(Like on a typewriter)
I come across this a lot having to convert #\Newline to
#\Return #\Newline. By the way a Mac used (does it still use?)
just #\Return. This is probably the reason for the routine.
I should have caught the problem myself. For Unix compatabillity
Emacs typically handles both cases for Windows and Unix.
So LispWorks for Windows handles #\Linefeed as #\Newline.
