Subject: [PATCH] Fixed _realpath() for UNC pathes like '\\examplepath\mypath'
 (will become '//examplepath/mypath'). See #1.

Here is a comparison between the output of the old and new version of _realpath():

Input: '/a/b/c/' Output old: '/a/b/c/' Output new: '/a/b/c'
Input: '//a/b/c' Output old: '/a/b/c'  Output new: '//a/b/c'
Input: 'a//b'    Output old: 'a/b'     Output new: 'a//b'
