//! `slu itag` - interactive tag explorer (TUI). The tags level of the drill,
//! entered directly: this repo's tags marked against its remote, the commits
//! each one added since the tag before it, and the diffs under those.
//!
//! git keeps no record of which tags a remote has, so the remote is asked with
//! `git ls-remote` once the screen is up. The marks stay blank until it
//! answers, and a remote that cannot be reached says so on the pane's title.
