patches: fix singleLineMove compile error - out-of-scope variables

oldLine and newLine were declared inside 'if (cachedText && oldPoint > 0)'
block but singleLineMove block referenced them from outside that scope.

Fix: declare singleLineMove = NO before the granularity detection block;
compute adjFwd/adjBwd inside the 'if (oldLine.location != newLine.location)'
branch where both variables are in scope.
