[Bug 35539] Proteus 8 demo fails to install

[WineHQ Bugzilla]

--- Comment #6 from Zebediah Figura  ---
This call:

010c:trace:msi:ITERATE_WriteEnvironmentString name L"=-*LXKSERVER" value
L"[KEY_SERVER]"

fails because KEY_SERVER isn't defined, which causes deformat_string() to
correctly return an empty string and 0 length, which
ITERATE_WriteEnvironmentString() interprets as failure.

It's possible KEY_SERVER should be defined, though, but definitely
WriteEnvironmentStrings is broken.

I've sent https://source.winehq.org/patches/data/204974.
