It flags the regexes whose search is quadratic in the input length, like the autolinker and XFA-path ones fixed recently. The three existing offenders: `\s*` matched the CSS indentation but also the line terminators that make `^` match with the `m` flag (the preprocessed CSS is unchanged), `(\d+)` made every digit of a number a candidate start position, and `/T.*$/` could fail on the `$` and backtrack since `.` doesn't match a line terminator.
