//! `helixforge report`: what a bug report needs to know about this copy of
//! HelixForge and this machine, to paste into an issue. It reads only, and
//! leaves out what is personal: the home directory is shown as `~`, there is
//! no host name, and the history gives entry names and results, not logs.
