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.

How to write RIGHT test cases ============================= Insert the word "ChangeMe" (exactly this form) at a distance of at least two lines from the line that must appear in the hunk header. The text that must appear in the hunk header must contain the word "right", but in all upper-case, like in the title above. To mark a test case that highlights a malfunction, insert the word BROKEN in all lower-case somewhere in the file. This text is a bit twisted and out of order, but it is itself a test case for the default hunk header pattern. Know what you are doing if you change it. BTW, this tests that the head line goes to the hunk header, not the line of equal signs.
