|
// state storage to avoid conlficting with user defined env names. This is
|
|
// used to preserve drive letter paths. E.g., typing c: from another drive
|
|
// will remember the last CWD because CMD stores it in an env named "=C:".

// Since these are illegal, they are filtered from standard user access but
|

// are still available in the underlying win32 API calls. Since they have
|
|
// zero value to a container, we filter as well.
