Diffstat path truncation: a path exactly as wide as the column is truncated · case 02

Paths that would fit are shortened with an ellipsis.

Member previewVariant 2 · 3 implementations · 7 checks per implementation

Case contract

A path longer than width is shown as "..." plus its last width-3 characters, further shortened to start at the first "/" inside that tail when there is one (keeping the slash). Paths not longer than width are unchanged.

Why this case matters

Narrow terminals truncate long paths in diffstat output; the rule keeps the most informative part of the path.
