--- Comment #7 from Rainer Jung <rainer.j...@kippdata.de> ---
I could now test the behavior. Unfortunately GetServerVariable does not return
size 0 but instead size 1 in this case. So it really returns an exmpty string
and there's no way to make a dstinction between a NULL and an empty string.
That means we have to make a distinction based on the semantics of the various
variables. I'll keep most of them as empty strings for compatibility and will
replace the empty string by NULL for REMOTE_USER. We can let it control by
another argument, so it will be easy to switch more variables from empty string
to NULL as the need arises.
