[pkg-wine-party] Bug#814572: Please print information output to stderr

[Erik de Castro Lopo]

Package: wine
Version: 1.8.1-1
Severity: normal

Wrapper scripts like /usr/bin/wineserver print informational
info to stdout instead of stderr.

My main usecase for Wine is to run program test suites when I
cross compile from Linux to Windows. Having these informational
messages on stdout and then having to remove them in my test
suite is inconvienient. If instead these messages were on stderr
I could just pipe stderr to /dev/null. In addition, I would be 
able to do it once in the test wrapper script instead of having
to deal with each program output separately.
