Hanging-indent list labels: label clearance · case 03

Labels exactly as wide as the hang touch the text.

Member previewVariant 3 · 3 implementations · 8 checks per implementation

Case contract

Input [label, words, width, hang]. The label starts at column 0; first-line text starts at column hang when label+1 space fits, else right after label plus one space. Continuation lines are indented by hang. Greedy fill with unit spaces measuring absolute columns. Return padded lines.

Why this case matters

Line breaking decides where paragraphs wrap on screen and in print; a wrong decision point shifts every following line.

One recorded failure
