From the "apparently I don't know C" files...GCC apparently supports:
x ?: y
which is equivalent to
x ? x : y
except that it doesn't cause side-effects to occur twice. See:
https://gcc.gnu.org/onlinedocs/gcc/Conditionals.html#Conditionals
This was confusing and looked like a typo. It doesn't really buy us
anything, so just write the obvious code in normal C.
