Yapf seems not work very well

[HarumiKiyama]

Description

I use the python layer and apply the function py-yapf-buffer twice, it works but append a ^M marker at the end of every line. And after I save the buffer, the ^M markers disappear and insert a blank line beneath every line.

I would be surprised if this is a Spacemacs problem. Have you tried what happens when you use yapf in the command line? This seems to be a Windows only problem since ^M are the Windows line endings.

Yes, you are right. Using yapf in command line make things done, there are no ^Mmakers any more.And I make a mistake in the issue description, I actually apply py-yapf-buffer twice.In the first time it works very well,but in the second time, ^M makers appear

WIth yapfify-buffer, I cannot reproduce on Linux.
