MSDN says a lot of things. On my XP SP2 it returns 1 as size when passed
an empty service name. Also failing here is a bit ambigeuos since the
dunction also fails when a NULL pointer is passed or the buffer is to
small, but it does change the size into what it expects in these two
cases.

I took this more or less directly from registry.c in the same directory.

This won't work for localized Windows versions. The display name is possibly
translated. Also, on XP SP2 the A function returns the size in ASCI chars
that
the W function will need in bytes. Not a behaviour I feel Wine should
imitate
without an app that would need that behaviour.

I'll be gone for two weeks for vacation. If anyone wants to continue on that
please feel free. Otherwise I'll be picking this up afterwards.
