lizard --sort cyclomatic_complexity --CCN 10 shows a file with CCN score of 1

[huornlmj]

Taking a well known and popular network port mapper's source code and scanning it with:

lizard --sort cyclomatic_complexity --CCN 10

The following is shown at the end of the report. I had expected there to only be files with cyclomatic complexity of above 10 shown, but as you can see there is a file included with a CCN of 1.
