Subject: [PATCH] Remove warning in wmagnify.c (correctly)

The problem with f65b99e615847 was that it removed the call to
newWindow() along with the unused variable, without considering that
newWindow() has side effects that need to happen even if the return
value is ignored. So as long as we keep the newWindow() call, we can
safely remove the (unused) variable.
