| # Lints only the lines a pull request adds or modifies, rather than whole | |
| # changed files. New and edited code must satisfy the linters, while | |
| # untouched legacy code in the same file is not flagged -- so lint rules | |
| # can be adopted or tightened incrementally as files are touched. | |
