As reported in https://github.com/mawww/kakoune/issues/4685#issuecomment-1200530001 ledger.kak defines a region end that matches every character of the buffer. This causes performance issues for large buffers. Since the affected regions are only ever filled with a single color, just use a regex highlighter instead of a region highlighter. This improves performance when loading the file for the first time.
