If lines are too long and make reading the source file harder, I'd
recommend externalizing the string instead (putting into the resource
file). If this is hard to do, I would leave it as is. Horizontal scrolling
is not a big problem, but left indentation breaks the flow in the common
case when you actually don't need to read the text block content. Well
"sometimes reasonable" looks ok to me, but I would not agree with Alex that
this should be "recommended".

With best regards,
