//! Implementation of the `UndoEdit` tool.
//!
//! Reverts a file to the content it had before the last `FileWriteOrEdit` /
//! `MultiFileEdit` in this session, using the in-memory checkpoint those tools
//! record (see `bash_state::EditCheckpoint`). Per-file LIFO: repeated undos on
//! one file walk its edits back. A brand-new file's creation has no prior content
//! and is not undoable.
