`find_target()` failed to match numbers followed by a dot and a non-digit (e.g. `1. item`), because the dot unconditionally reset the scan state, discarding the number. Additionally, numbers at the start of non-first lines were missed because the backward scan stopped on the preceding newline and the forward scan immediately broke on it. Closes #47761 Release Notes: - Fixed vim increment (`ctrl-a`) and decrement (`ctrl-x`) not working on Markdown ordered list markers like `1.`, `2.`, etc. --------- Co-authored-by: Claude Opus 4.5 <noreply@anthropic.com> Co-authored-by: dino <dinojoaocosta@gmail.com>
