It's not easy.  If we remove the new behaviour entirely, we break
other scenarios which were broken in the old version.  While it
*seems* easy to fix your specific scenario, it will break again
as soon as the substitution drive is used inside a native symlink.

Virtual drive letters were always a problem and it doesn't get easier
with Windows functions not allowing to specify whether one wants to
follow symlinks or virt drives in inner path components or not.

Let's consider this problem again, but I don't see a quick and easy
solution.
