The graph gives up text for shape: a 260px row has room for about 26 characters beside its lanes, and this repository's commit subjects run to a median of 64. This is where the rest comes back — the full subject, the body, every ref, the parents, and the files the commit touched. The file list is two commands, not one. Git accepts `--numstat` and `--name-status` together and then quietly drops the numstat half (measured on 2.50.1), so they run separately and join on the path. It is `log -1 --first-parent` rather than `diff-tree -m --first-parent`, which does not narrow a merge: on the same git it emits one diff per parent and concatenates them, so a two-parent merge came back with every path listed twice. `log` is also how `DiffSource::Commit` walks the patch, which is what makes this list and the overlay's cards agree file for file. `DiffSource::Commit` now carries an optional label, so the overlay's header can say what the commit was about instead of eight hex digits. The label deliberately takes no part in the source's identity: `PartialEq`, `Hash` and the overlay's string probe key are all derived from one `tag()` function, because the same commit opened with a subject in hand and without one has to stay one patch, one in-flight probe and one overlay. The key used to be built from `Debug`, which would have split the probe cache the moment a label arrived. Also lifts `local_branches` out of the panel's inline `for-each-ref`, and keeps the `%(upstream)` that `parse_refs` had been asking for and throwing away.
