OK, thanks to Bill, Paul, and Dave for the explanation of what happened and
why it happened.

Now, how to fix it? (I'm assuming it is something that we want to fix.) I
can easily convert all the \r\r\n to \r\n. (This is on a Windows machine.)

If that leaves any stray \r not followed by \n, add the missing \n. (This
fixes any files edited on a Mac or having \r not followed by \n for other

Then just do a regular commit? or a forced commit? I guess I could try on
one file first to make sure it works as expected.

Dave, would you like me to do that, or would you rather fix the files
