If one saves an environment variable that is a blank string, and then retrieves
that value, the returned value is the null string.
While this normally would be fine (null is a valid blank string), the get
function uses null as a sentinel to signify that the environment variable isn't
present. This means one cannot distinguish between getting an environment
variable that is blank, and one that is missing.
