[PATCH 0/1] MR9414: Draft: shlwapi: Handling of "C:\...xx" in PathCanonicalize[AW].

[Thomas Csovcsity (＠thc13)]

## Description

This is intended to solve https://bugs.winehq.org/show_bug.cgi?id=58129

Add tests for verification, which pass on my locale win10 machine.

##Todo
 - [] Removed UNC path check which seems okay, but i am not sure why it was introduced. git blame did not help me, therefore any hints or examples to test are welcome.
