Well it's not test (or even the test built-in in bash) that strips out

a variable. I don't know whether it would be a good idea for it to strip 
\r as well.

I think what needs to be fixed is the expectation that you can mix 
non-Cygwin Python with Cygwin everything else and things will work 
seamlessly. ;)
