As explained in #1060, I am unable to replicate the issue to warrant this PR.

There shouldn't be any need to hardcode the pattern \ and / as it is handled by path.sep.

path.sep

Added in: v0.7.9

Provides the platform-specific path segment separator:

• \ on Windows
• / on POSIX

For example, on POSIX:

'foo/bar/baz'.split(path.sep);
// Returns: ['foo', 'bar', 'baz']

On Windows:

'foo\\bar\\baz'.split(path.sep);
// Returns: ['foo', 'bar', 'baz']

On Windows, both the forward slash (/) and backward slash (\) are accepted as path segment separators; however, the path methods only add backward slashes (\).
