Fs: Fix UNC remapping code.
For a Win32 path such as C:\foo
we rewrite it to \\?\C:\foo
. For a network share \\foo\bar
this needs to become \\?\UNC\foo\bar
but we were accidentally making it \\?\UNC\\foo\bar
notice the double \\
. That's an invalid path.
Change tested manually using a local path accessed through \\localhost\c$\<path>
Fixes #17788 (closed)
@bgamari are you still using the binary patcher for the 8.10 release? If so I'll update it with the fix tonight.
