This function has a block conditional on !snd_wnd_cap shortly before an
#ifdef HAS_SND_WND. But snd_wnd_cap implies HAS_SND_WND (if !HAS_SND_WND,
snd_wnd_cap is statically false).
Therefore, simplify this down to a single conditional with an else branch.
While we're there, fix some improperly indented closing braces.
