--- Comment #2 from Jason Edmeades  ---
Its not created without an empty name, they have a name starting with an equals
sign. Please see the comments from when the patch was originally requested

On windows, try "echo %=c:%" for example...

I suspect these are masked from the application depending on how they query the
environment somehow
