That's not simpler, it's now harder to read and parse.  Only use ?: in C
for places it has to be used, not for stuff like this where it's more
obvious if you use an if () line.

We write code for people first, compilers second.

Also, you can't do two different things in the same commit, sorry.

thanks,
