Markdown writer: changes to `--reference-links`. With `--reference-location` of `section` or `block`, pandoc will now repeat references that have been used in earlier sections. The Markdown reader has also been modified, so that exactly repeated references do not generate a warning, only references with the same label but different targets. The idea is that, with references after every block, one might want to repeat references sometimes. Closes #3701. 2017-05-27 21:41:47 +02:00			```
