minirst: detect bullet lists using asterisks Previously, the "bullet" regular expression excluded the asterisk ('*') as a character denoting a bulleted list. Why I'm not sure because the asterisk seems to be the canonical bullet character in reST these days. This patch makes asterisk-prefixed lines parse as bulleted lists.
