Pacman 5.0.2

# pacman -S --asdeps npm

npm depends on nodejs while nodejs optionally depends on npm. In this case

$ pacman -Qdt npm

prints nothing and exits with 1.

I'm used to use `pacman -Qdtq | sudo pacman -Rsn -` to remove orphans but it doesn't work for npm package which I install sometimes to build some packages.
This task depends upon

-t, --unrequired list packages not (optionally) required by any package (-tt to ignore optdepends) [filter]

pacman -Qttd lists npm.

Yes, but it's correct to have optional dependencies installed as dependencies, in this case I can keep optional packages dependent on some package and remove all these packages with the explicitly installed package in the future. I always install optional dependencies with --asdeps flag. So of course I can't use `pacman -Qdttq | sudo pacman -Rsn -` since it will remove optional dependencies I'm keeping as dependencies which are needed for me.

Both npm and nodejs installed as dependencies, there are no explicit packages dependent on them. But they aren't listed with pacman -Qdt. The behavior I'm talking about in the report is definitely incorrect.

npm is an optional dependency for for nodejs
nodejs is a dependency for for npm semver

"pacman -Qtd" will not show it as both packages are required or optionally required by other packages.
"pacman -Qttd" does show it, because npm is not directly required by anything.

So this is working completely as documented.
