Extended Description

The following code is parsed fine by Doxygen and correctly rendered as a hyperlink without any warnings - but -Wdocumentation gives a warning.

$ cat test.c
/**

• <a
• href="http://example.com/">test
  */
  int main(void) {
  return 0;
  }
  $ clang -Werror=documentation test.c
  test.c:3:2: error: HTML start tag prematurely ended, expected attribute name or '>' [-Werror,-Wdocumentation]
• href="http://example.com/">test
  ^
  test.c:2:5: note: HTML tag started here
• <a
  ^
