`npm ls <pkgname>` always exits in error (even when there are no ls problems)

This is weird...

$ node . ls eslint
npm@7.0.2 /Users/isaacs/dev/npm/cli
├─┬ eslint-plugin-import@2.22.1
│ └── eslint@7.11.0 deduped
├─┬ eslint-plugin-node@11.1.0
│ ├─┬ eslint-plugin-es@3.0.1
│ │ └── eslint@7.11.0 deduped
│ └── eslint@7.11.0 deduped
├─┬ eslint-plugin-standard@4.0.1
│ └── eslint@7.11.0 deduped
└── eslint@7.11.0

$ echo $?
1

I'm surprised that if npm ls exits nonzero, that some kind of warning wouldn't automatically be generated on npm install?

is this still an issue? i'm not able to reproduce it from latest on my end

this was fixed in 7.0.3
