Avoid an extra function call by using a ternary operator instead of
a conditional statement for a setting selection.

This issue was detected by using the Coccinelle software.

Unless you use an upstream coccinelle script or you share the one you
are using, this is not a useful information.

This makes the code less readable.

How do you think about to extend a software development discussion
on a topic like “Pretty-printing of code for ternary operators?”?
