Description

This bug looks like a windows line-ending (CRLF) vs. unix line ending (LF) problem. I.e., real bug in test because it is line-ending sensitive. When I look at this in Emacs it shows me the CRs as ^M. Every line ends with a ^M except the ones I marked with ### below.
THere are several of this same failure. These are tests related to internal whitespace preservation, so it's a place where Windows vs. Linux sensitivity may come up.

We need to change these tests so they are portable somehow.
