You would appear to be using Windows console cmd builtin echo, which adds \r
before \n, instead of another shell builtin echo.
Your results are not consistent with what I get running under either cmd, where
" quotes and \r are always passed thru, or Cygwin bash, where " quotes are
stripped but \r is always passed thru using cmd /c echo.
Are you using settings or an msys or mingw shell that uses different rules from
current Cygwin defaults?
The results from commands "type -a echo" and "which -a echo" may shed light.
