Most likely, it is a combination of the MinGW libc (which emits "\r\n" 
for end-of-line in accordance with Windows convention) and the kernel 
terminal driver (which passes "\r" and translates "\n" to "\r\n" in 
accordance with POSIX convention).  Wine, short of trying to translate 
"\r\n" back to "\n" in accordance with POSIX conventions (and likely 
making an even bigger mess---does Wine know if a handle is supposed to 
be text or binary?) cannot really fix this, so the testsuite needs to 
handle non-POSIX-standard line endings.  (The Rust tests probably have 
an outright bug if the newlines are being duplicated.)
