I'm testing what happens if the setmode() call is removed in my next
build of bash for cygwin; I can't figure out why text mode would be
desirable in the first place, but even if it is desirable, it should
only eat \r immediately before \n, not \r before other bytes.  This may
be stale leftover code from years ago that doesn't make sense to keep
