If I have to use --verbose, to understand that the warning is about me
writing 3 lines when the script expects 4, I don't think it's
particularly user friendly.

Let's write "Expected 4+ lines" or something equally clear.
It will fit in a row and get the job done.

It's all good in general, but here the word "paragraph" is being abused,
in the sense that it has been given an arbitrary meaning of "4 lines".
And the warning is even worse because it doesn't even acknowledge that I
wrote something, even if it's a meager 1 or 2 lines.
Which is even more confusing.

As user, if I'm running checkpatch.pl and I get a warning, I should
spend my time trying to decide if/how to fix it, not re-invoking it with
extra options or reading its sources.
