If the test suite runs Diff, it should invoke it with the "--strip-trailing-cr" switch, I think. Because Cygwin's (and MSYS's) Diff doesn't use Windows text-mode I/O. The tests succeed here, because I made 'diff' a shell script that runs the "real" Diff with --strip-trailing-cr. I found long ago that many test suites have this problem, so I fixed it once and for all.
