First, I think now the most common option to choose when you have to wrap your code is this one:
(or almost the most common I've seen people are used to)
But let me say to you that there is another suitable option, that in my opinion is better.
What this option does is, to keep the whole lines into the source code, and then
to cut them at a position, the one that you've chosen.
For example, here is the selection at first.
Then, this result has the following effect:
Then, if we save the code, it's keeping and showing with this line larger than our expectations...
So, we have to toggle to this option:
Then, the result is the following:
SO, briefly, this option keep the source code "as it", but the only thing is that it "truncates" the code,
and to put it immediately at down first position.
I think this option is better, because it keeps the source code unchanged, and then you can choose
on which position is going to be better to be truncated.
Hope it helps.
