Nice patch, thanks Arturo!
Why make this an option in first place?

How hard would it be to make it so that this is still
printed in single line (enough space left)?

Printing all addresses in a single line is unreadable, it seems
strange to have an option to make it nice and then make 'unreadable'
the default :)
