In the process of changing paths from using exe to using bin in my
sandbox, I edited dacdif (which contained such a path, albeit in a
comment) using a Mac GUI text editor. One of dacdif's sed patterns
replaces whatever newline is indicated by ^M - I think a carriage return
- with an empty string. But the ^M got automatically turned into a line
feed for me, and then when using dacdif (as when running the tests) I
would get nice little messages about how the a pattern isn't complete.

In my own sandbox, I rolled it back. But in the course of my fixing all
copies of dacdif, I ran into the fact that there were three independent
copies of it. Hence this email.
