Not at all. New line, so tab the next line over as far as it will go
without falling off the 80-column limit. It's fairly common.
To quote Documentation/CodingStyle:
Statements longer than 80 columns will be broken into sensible chunks.
Descendants are always substantially shorter than the parent and are placed
substantially to the right. The same applies to function headers with a long
argument list. Long strings are as well broken into shorter strings. The
only exception to this is where exceeding 80 columns significantly increases
readability and does not hide information.

Thanks, fixed.

Empty line not necessary.

Because it then looks the same as the other two cases where we can error
out.

So if I remove them today, the command will still work?
