wrapping: when autoindenting, use indentation of next line as example

Browse Source 
When doing autoindentation, and the next line is not the start of
a new paragraph, then use the indentation of that line for the new
line, as it is more likely to have the desired indentation -- the
current line might be the start of the paragraph and thus could
have a deviant indentation.
