Bug ID: 58444
           Summary: winepath -w "$PWD" outputs corrupted Windows path with
                    extra garbage
           Product: Wine-staging
           Version: 10.11
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

After updating to Wine 10.11 (staging), I noticed that winepath -w "$PWD"
produces corrupted output.
At the end of the result, containing some "fixme" messages, there's an invalid
path segment such as:

Z:\home\michaechael

My username is michael, and the extra michaechael is not present in the
filesystem or Wine prefix.

Additional info:

echo %USERPROFILE% returns correct C:\users\michael

No michaechael user exists under drive_c/users

grep -i michaechael ~/.wine/*.reg returns nothing

ls ~/.wine/drive_c/users contains only michael and Public

This did not happen in Wine 10.10

I suspect a regression or buffer corruption in winepath.
