Lets please keep the comments inline instead of top-posting, as for
the formatting Id say we should fix this in bt_shell so it actually
detects if the line should be broken or not. We may as well truncate
if that doesn't fit into the terminal, but that should be done generic
so the commands don't need to come up with their own way of
formatting.
