When newline_style is set to Windows, an empty line inside of a macro results in `\r` being passed to the `fold()` in `MacroBranch::rewrite()`. `\r` is technically not an empty string, so we try to indent it, leaving trailing whitespaces behind, even though that was not intended (as far as I can see). This commit replaces the `!l.is_empty()` check with calling `is_empty_line()`, since trying to indent any whitespace-only string will probably result in problematic trailing whitespaces. Fixes: #2810 |
