pub fn run_wizard() -> Result<()>Expand description
Walk the global settings, offering each current value for confirmation.
Run once by hand as devp config wizard, and once automatically the first time a
human types a command on a fresh install — the point at which every default is about
to start applying to their machine, and the only point at which they can be told so
before rather than after.
Refuses without a terminal instead of hanging on a read that will never return.
