For some reason, calling `AssocQueryStringW` on Windows Home returns error
code 122, "The data area passed to a system call is too small", even when
the data area is large enough. Furthermore, the API actually describes that
in such cases `S_FALSE` is supposed to be returned, with `*pcchOut` set to
the required size. Because of this apparent violation of the documentation,
and because it just works, Flamenco now ignores this particular error and
just returns the obtained string.
