You're telling this person to use more lines, but not telling them to
add comments, yet that is the reasoning behind the very CodingStyle
recommendation you are quoting.

I think you're recommendation is gratuitous and in my opinion wrong.
Splitting up the line adds no value, and makes the function take up
more lines on the terminal screen.
