The statement "os.path.realpath('C:\\Users\\')" returns different results between 3.6.6 and 3.6.7 (and between 3.7.0 and 3.7.1) on Windows.
With python 3.6.6 and 3.7.0 I got 'C:\\Users'.
With python 3.6.7 and 3.7.1 I got 'C:\\Users\\'.
Note the extra trailing backslash with python 3.6.7 and 3.7.1.

On Linux the behavior is consistent where the trailing slash in the input will be remove from the output: os.path.realpath('/home/') --> '/home'.

I think we should keep the behavior of removing trailing backslash on Windows.

Thanks.

realpath aliases to abspath in Windows as I can see from the code and I think this is a regression fixed with https://github.com/python/cpython/pull/10082
