Subject: [PATCH] Add code comment to ease understanding
As I'm [not the only one](https://github.com/VividCortex/go-database-sql-tutorial/issues/70) who stumbled upon this, let's just add a comment to the example code.
No logging library I have worked with goes as far as terminating the program, so many go beginners may not understand this - although I think it does make sense. (Otherwise - what's the meaning of "fatal"?)
