MarsSeed [1] filed a deletion request for nfu-git [2]: Unneeded, unused VCS package from 2015. Since 2017, upstream is not maintained, and its developer instead shifted their focus to a successor project. [a] As per project README: "nfu: Numeric Fu for your shell NOTE: nfu is unlikely to receive any more major updates, as I'm currently working on its successor ni."
