Deletion of Sino-Vietnamese wars

Comment: but it's a little more complicated.  There's actually ''three'' titles involved here.  We're talking about Sino-Vietnamese wars (plural) here.  There's also Sino-Vietnamese War (singular) which is a detailed article about the 1979 conflict, and Sino-Vietnamese War (disambiguation) which covers several millennia.  So, I think merge this into Sino-Vietnamese War (disambiguation) just to make sure we've got complete coverage, and redirect this title to there.  However, I would not keep the summary text from here, since that's specific to one particular conflict, and seems kind of -ish.  I'll take a shot at merge and cleanup now
Stance: merge
