Comment 1 for bug 720517

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.
