Patch #2 makes use of "d" in the first "if" branch also. I don't think
it makes much sense to put it inside of the "else if" branch if I have
to move it in the following patch.

Regarding the name, I don't have a strong opinion, desc is more
descriptive, but it's also longer which means I might have to break some
lines inside of the macro even more.
