Bug Description

1. A very clear description of the requirements and associated problems is in CLtL2, section 2.2.2. "Line Divisions", online here:

http://www.cs.cmu.edu/Groups/AI/html/cltl/clm/node23.html

2. Write the following code into a Lisp file in a plain text editor (e.g., Notepad) on Windows and then LOAD the resulting file.

(format t "~:c" (char "
" 0)) ; Should print Newline

It should print Newline. Otherwise, it's a bug. On SBCL it prints Return.

While hairs can be endlessly split on if this is strictly required or not, the fact remains that we _do_ want it to work in SBCL.

Not marking as a duplicate of #310185 to make it clear that this can be considered a defect -- not just a wishlist item.

Marking as High-importance, since if someone needs to work with a codebase containing CRLFs, this is extremely annoying to work around.

Changed in sbcl:
importance: Undecided → High
status: New → Triaged
