// ── Sourcehut (todo.sr.ht) ───────────────────────────────────────────────────
//
// Sourcehut's bug tracker lives on a separate subdomain from the git
// host. The convention is `~user/<tracker-name>` where tracker name is
// usually the same as the repo (but not enforced) — projects sometimes
// have multiple trackers (e.g. `-bugs`, `-features`). We assume
// `tracker_name == repo_name`; if the user uses a different naming
// scheme they can pass `--remote` to a remote whose URL points at the
// correct tracker (in 0.8.0 with platforms.toml this will be
// configurable per-host).
