userdiff: support Markdown
It's typical to find Markdown documentation alongside source code, and having better context for documentation changes is useful; see also commit 69f9c87d4 (userdiff: add support for Fountain documents, 2015-07-21). The pattern is based on the CommonMark specification 0.29, section 4.2 <https://spec.commonmark.org/> but doesn't match empty headings, as seeing them in a hunk header is unlikely to be useful. Only ATX headings are supported, as detecting setext headings would require printing the line before a pattern matches, or matching a multiline pattern. The word-diff pattern is the same as the pattern for HTML, because many Markdown parsers accept inline HTML.
