I think it would help your cause if you quoted the exact piece of code
you're referring to.  Then tone down the language a bit - keep it as
simple and natural as you can.

Ex 1: Please place curly brackets around this section to aid with <reason>

Ex 2: To save N lines of clean-up, please use scoped_guard()

Ex 3: Moving out this chunk to another function would help with <reason>

Etc.
