The code was supposed to loop 10 times but it loops 11 times because it
uses a post op instead of pre op. Using parenthesis doesn't affect how
post ops work.
Also I have clarified the comment. Hopefully I understood the intent
correctly.

Static checkers stuff. I haven't tested this. I was auditing for post
op vs pre op increments. It turns out that some people always put
parenthesis around increment operations for style reasons so it's also
possible that the intent was to loop 11 times.
