Description:
------------
From Bug #61441

[2012-03-20 10:06 UTC] pajoye@php.net
Expected behavior. All files operations working with paths to clean or resolve 
them returns the OS specific directory separator.

@pajoye: Is this in the PHP documentation anywhere?  I cannot find it in 
http://php.net/manual/en/function.readlink.php or the parent 
http://www.php.net/manual/en/ref.filesystem.php

Should I file a missing documentation bug?

Thanks!

Expected result:
----------------
Filesystem-related functions or parent Filesystem pages in documentation should 
clearly state what sort of directory separators will be returned (OS-specific, or 
OS-agnostic)



Actual result:
--------------
There is indication of support for Windows for many of the filesystem functions, 
but no clear documentation stating how these functions will return directory 
separators.
