Copter: Changing the description of increments and decrements

I know that the increment and decrement operators have a preamble and a postamble.
I preface it with an incremental, decriminalization first.
I can make it one line if I understand the priority of C++.

This won't bring any benefit on optimised build, I don't think those kind of micro optimisation are worth it on this part of the code

yeah, i think I'll close this one, thanks.
