[pkg-go] Bug#801593: Bug#801593: ratt does not find all reverse build dependencies

[Michael Stapelberg]

With an arbitrarily selected package, I’m not getting the expected result —
dose-ceve lists fewer dependencies than ratt:

Running ratt as-is:

$ go run ratt.go -dry_run

Do you know where that difference comes from?
