Snowballing -2 lemma

The snowballing -2 lemma states that in MediaWiki,

• given a proposed change with uncertain consensus,
• if a -2 is placed over the change to prevent its merge,

then it's immediately certain that the change will eventually receive a +2.

The interim name of the lemma derives from the m:Snowball clause: a -2, in fact, declares in advance of closure that there is a consensus for merge. Otherwise, there would be no need to try to prevent the merge with force.
