Great! Yes, I couldn't see a good place to add a test for this. I did verify that it works on a running Windows Server 2019 VM. |

We observed that on Windows, symlinks from the
C:\base directory such asC:\Userswere being resolved asC:\C:\Users. In this PR, we do not join the base directory to the resolved symlink if it is already there.On Linux, having a path such as
//usr/local/bindoes not cause any issues (and the//is converted to/infilepath.Clean) butC:\C:\does not work, and is not converted toC:\infilepath.Clean(go playground example)We also noticed that if there is a symlink from the
C:\drive to another drive such asD:\, this code correctly resolves the path, and does not have a path that starts withC:\D:\Fixes #1950 (we think)
