Fix conjunction placement

[TadeasKucera]

In case of a conjunction preceded by some newlines and a one-line comment:

		true // cuckoo

		and false

our autoformatter wrongly created

		true // cuckoo and
		false

This is fixed in this PR, where

		//cuckoo
		cuckoo.sync.mutex(/a/)
		
		or cuckoo.sync.mutex(/b/)
		
		//cuckoo

	
		or cuckoo.sync.mutex(/c/)




		or cuckoo.sync.mutex(/d/)

becomes this

		//cuckoo
		cuckoo.sync.mutex(/a/) or
		cuckoo.sync.mutex(/b/) or
		//cuckoo
		cuckoo.sync.mutex(/c/) or
		cuckoo.sync.mutex(/d/)
